## lbry-rocksdb
|
||||
|
||||
### Note
|
||||
The `python-rocksdb` and `pyrocksdb` packages haven't been updated in a long time - this repo is a fork of python-rocksdb with many of the PRs to it merged, and with [bunch of updates and improvements](https://github.com/iFA88/python-rocksdb) from @iFA88 and @mosquito.
|
||||
|
||||
|
||||
### Install from pip
|
||||
pip install lbry-rocksdb
|
||||
|
||||
|
||||
### Install for development / from source
|
||||
sudo apt install build-essential binutils
|
||||
git clone https://github.com/lbryio/lbry-rocksdb.git
|
||||
cd lbry-rocksdb
|
||||
git submodule update --init --recursive
|
||||
git pull --recurse-submodules
|
||||
make clean && make
|
||||
pip install -e .
|
||||
python -m unittest discover . -v
|
||||
|
||||
|
||||
### Quick Usage Guide
|
||||
>>> import rocksdb
|
||||
>>> db = rocksdb.DB("test.db", rocksdb.Options(create_if_missing=True))
|
||||
>>> db.put(b'a', b'data')
|
||||
>>> print db.get(b'a')
|
||||
b'data'

Welcome to python-rocksdb's documentation!
|
||||
==========================================
|
||||
|
||||
Overview
|
||||
--------
|
||||
Python bindings to the C++ interface of http://rocksdb.org/ using pybind11::
|
||||
|
||||
import pyrocksdb
|
||||
db = pyrocksdb.DB()
|
||||
opts = pyrocksdb.Options()
|
||||
# for multi-thread
|
||||
opts.IncreaseParallelism()
|
||||
opts.OptimizeLevelStyleCompaction()
|
||||
opts.create_if_missing = True
|
||||
s = db.open(opts, '/path/to/db')
|
||||
assert(s.ok())
|
||||
# put
|
||||
opts = pyrocksdb.WriteOptions()
|
||||
s = db.put(opts, b"key1", b"value1")
|
||||
assert (s.ok())
|
||||
# get
|
||||
opts = pyrocksdb.ReadOptions()
|
||||
blob = db.get(opts, b"key1")
|
||||
print (blob.data) # b"value1"
|
||||
print (blob.status.ok()) # true
|
||||
#delete
|
||||
opts = pyrocksdb.WriteOptions()
|
||||
s = db.delete(opts, b"key1")
|
||||
assert(s.ok())
|
||||
db.close()

Basic Usage of python-rocksdb
|
||||
*****************************
|
||||
|
||||
Column Family
|
||||
=============
|
||||
|
||||
python-rocksdb also supports column family ::
|
||||
|
||||
db = pyrocksdb.DB()
|
||||
opts = pyrocksdb.Options()
|
||||
opts.create_if_missing = True
|
||||
s = db.open(opts, 'path/to/db')
|
||||
# create new column family
|
||||
copts = pyrocksdb.ColumnFamilyOptions()
|
||||
s, cf = db.create_column_family(copts, "new_cf")
|
||||
del cf
|
||||
db.close()
|
||||
# open db with the column families
|
||||
cfd1 = pyrocksdb.ColumnFamilyDescriptor(pyrocksdb.DefaultColumnFamilyName, pyrocksdb.ColumnFamilyOptions())
|
||||
cfd2 = pyrocksdb.ColumnFamilyDescriptor("new_cf", pyrocksdb.ColumnFamilyOptions())
|
||||
cfds = pyrocksdb.VectorColumnFamilyDescriptor()
|
||||
cfds.append(cfd1)
|
||||
cfds.append(cfd2)
|
||||
db_opts = pyrocksdb.DBOptions()
|
||||
# column family handles
|
||||
s, cfhs = db.open(db_opts, 'path/to/db', cfds)
|
||||
assert(s.ok())
|
||||
assert(len(cfhs) == 2)
|
||||
assert(cfhs[0].get_name() == pyrocksdb.DefaultColumnFamilyName)
|
||||
assert(cfhs[1].get_name() =='new_cf')
|
||||
|
||||
wopts = pyrocksdb.WriteOptions()
|
||||
ropts = pyrocksdb.ReadOptions()
|
||||
s = db.put(wopts, cfhs[0], b'key', b'value')
|
||||
assert(s.ok())
|
||||
b = db.get(ropts, cfhs[0], b'key')
|
||||
assert(b.status.ok())
|
||||
assert(b.data == b'value')
|
||||
b = db.get(ropts, cfhs[1], b'key')
|
||||
assert(b.status.is_not_found())
|
||||
|
||||
s = db.put(wopts, cfhs[1], b'key', b'value2')
|
||||
assert(s.ok())
|
||||
b = db.get(ropts, cfhs[1], b'key')
|
||||
assert(b.status.ok())
|
||||
assert(b.data == b'value2')
|
||||
|
||||
b = db.get(ropts, cfhs[0], b'key')
|
||||
assert(b.status.ok())
|
||||
assert(b.data == b'value')
|
||||
|
||||
s = db.delete(wopts, cfhs[0], b'key')
|
||||
assert(s.ok())
|
||||
b = db.get(ropts, cfhs[0], b'key')
|
||||
assert(b.status.is_not_found())
|
||||
|
||||
s = db.delete(wopts, cfhs[1], b'key')
|
||||
assert(s.ok())
|
||||
b = db.get(ropts, cfhs[1], b'key')
|
||||
assert(b.status.is_not_found())
|
||||
|
||||
# write batch
|
||||
update = pyrocksdb.WriteBatch()
|
||||
update.put(cfhs[0], b'key1', b'value1')
|
||||
update.put(cfhs[0], b'key2', b'value2')
|
||||
update.delete(cfhs[0], 'key1')
|
||||
s = db.write(wopts, update)
|
||||
assert(s.ok())
|
||||
b = db.get(ropts, cfhs[0], b'key1')
|
||||
assert(b.status.is_not_found())
|
||||
b = db.get(ropts, cfhs[0], b'key2')
|
||||
assert(b.status.ok())
|
||||
assert(b.data == b'value2')
|
||||
|
||||
for cfh in cfhs:
|
||||
del cfh
|
||||
db.close()
|
||||
|
||||
|
||||
Wrtie Batch
|
||||
===========
|
||||
|
||||
It is also possible to gather modifications and
|
||||
apply them in a single operation ::
|
||||
|
||||
update = pyrocksdb.WriteBatch()
|
||||
|
||||
# collect the operations
|
||||
update.put(b'key1', b'value1')
|
||||
update.put(b'key2', b'value2')
|
||||
update.delete(b'key1')
|
||||
|
||||
opts = pyrocksdb.WriteOptions()
|
||||
# Apply these operatios in a single operation
|
||||
s = db.write(opts, update)
|
||||
|
||||
assert s.ok()
|
||||
opts = pyrocksdb.ReadOptions()
|
||||
blob = db.get(opts, b'key1')
|
||||
assert blob.status.is_not_found()
|
||||
blob = db.get(opts, b'key2')
|
||||
assert blob.status.ok()
|
||||
assert blob.data == b'value2'
|
||||
|
||||
db.close()
|
||||
|
||||
Iteration
|
||||
=========
|
||||
|
||||
Iterators behave slightly different than expected. Per default they are not
|
||||
valid. So you have to call one of its seek methods first ::
|
||||
|
||||
opts = pyrocksdb.WriteOptions()
|
||||
s = {b'key1': b'value1', b'key2': b'value2', b'key3': b'value3'}
|
||||
for k, v in s.items():
|
||||
db.put(opts, k, v)
|
||||
|
||||
opts = pyrocksdb.ReadOptions()
|
||||
it = db.iterator(opts)
|
||||
it.seek_to_first()
|
||||
assert it.status().ok()
|
||||
assert it.valid()
|
||||
for k, v in s.items():
|
||||
assert it.key() == k
|
||||
assert it.value() == v
|
||||
it.next()
|
||||
|
||||
assert not it.valid()
|
||||
|
||||
it.seek(b'key1')
|
||||
assert it.valid()
|
||||
assert it.key() == b'key1'
|
||||

<h3>Backward Incompatible Changes:<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h3>
|

<p><strong>Prefix Seeks:</strong></p>
|
||||
<p>According to this page <a class="reference external" href="https://github.com/facebook/rocksdb/wiki/Prefix-Seek-API-Changes">https://github.com/facebook/rocksdb/wiki/Prefix-Seek-API-Changes</a>,
|
||||
all the prefix related parameters on <code class="docutils literal notranslate"><span class="pre">ReadOptions</span></code> are removed.
|
||||
Rocksdb realizes now if <code class="docutils literal notranslate"><span class="pre">Options.prefix_extractor</span></code> is set and uses then
|
||||
prefix-seeks automatically. This means the following changes on pyrocksdb.</p>
|
||||
<ul class="simple">
|
||||
<li><p>DB.iterkeys, DB.itervalues, DB.iteritems have <em>no</em> <code class="docutils literal notranslate"><span class="pre">prefix</span></code> parameter anymore.</p></li>
|
||||
<li><p>DB.get, DB.multi_get, DB.key_may_exist, DB.iterkeys, DB.itervalues, DB.iteritems
|
||||
have <em>no</em> <code class="docutils literal notranslate"><span class="pre">prefix_seek</span></code> parameter anymore.</p></li>
|
||||
</ul>
|
||||
<p>Which means all the iterators walk now always to the <em>end</em> of the database.
|
||||
So if you need to stay within a prefix, write your own code to ensure that.
|
||||
For DB.iterkeys and DB.iteritems <code class="docutils literal notranslate"><span class="pre">itertools.takewhile</span></code> is a possible solution.</p>

BackupEngine
|
||||
============
|
||||
|
||||
.. py:class:: rocksdb.BackupEngine
|
||||
|
||||
.. py:method:: __init__(backup_dir)
|
||||
|
||||
Creates a object to manage backup of a single database.
|

Database interactions

Database object
|
||||
===============
|
||||
|
||||
.. py:class:: rocksdb.DB
|
||||
|
||||
.. py:method:: __init__(db_name, Options opts, read_only=False)
|
||||
|
||||
:param unicode db_name: Name of the database to open
|
||||
:param opts: Options for this specific database
|
||||
:type opts: :py:class:`rocksdb.Options`
|
||||
:param bool read_only: If ``True`` the database is opened read-only.
|
||||
All DB calls which modify data will raise an
|
||||
Exception.
|
||||
|
||||
|
||||
.. py:method:: put(key, value, sync=False, disable_wal=False)
|
||||
|
||||
Set the database entry for "key" to "value".
|
||||
|
||||
:param bytes key: Name for this entry
|
||||
:param bytes value: Data for this entry
|
||||
:param bool sync:
|
||||
If ``True``, the write will be flushed from the operating system
|
||||
buffer cache (by calling WritableFile::Sync()) before the write
|
||||
is considered complete. If this flag is true, writes will be
|
||||
slower.
|
||||
|
||||
If this flag is ``False``, and the machine crashes, some recent
|
||||
writes may be lost. Note that if it is just the process that
|
||||
crashes (i.e., the machine does not reboot), no writes will be
|
||||
lost even if ``sync == False``.
|
||||
|
||||
In other words, a DB write with ``sync == False`` has similar
|
||||
crash semantics as the "write()" system call. A DB write
|
||||
with ``sync == True`` has similar crash semantics to a "write()"
|
||||
system call followed by "fdatasync()".
|
||||
|
||||
:param bool disable_wal:
|
||||
If ``True``, writes will not first go to the write ahead log,
|
||||
and the write may got lost after a crash.
|
||||
|
||||
.. py:method:: delete(key, sync=False, disable_wal=False)
|
||||
|
||||
Remove the database entry for "key".
|
||||
|
||||
:param bytes key: Name to delete
|
||||
:param sync: See :py:meth:`rocksdb.DB.put`
|
||||
:param disable_wal: See :py:meth:`rocksdb.DB.put`
|

:raises rocksdb.errors.NotFound: If the key did not exists
|
||||
|
||||
.. py:method:: merge(key, value, sync=False, disable_wal=False)
|
||||
|
||||
Merge the database entry for "key" with "value".
|
||||
The semantics of this operation is determined by the user provided
|
||||
merge_operator when opening DB.
|
||||
|
||||
See :py:meth:`rocksdb.DB.put` for the parameters
|
||||
|
||||
:raises:

|
||||
|
||||
|
||||
.. py:method:: write(batch, sync=False, disable_wal=False)
|
||||
|
||||
Apply the specified updates to the database.
|
||||
|
||||
:param rocksdb.WriteBatch batch: Batch to apply
|
||||
:param sync: See :py:meth:`rocksdb.DB.put`

.. py:method:: get(key, verify_checksums=False, fill_cache=True, snapshot=None, read_tier="all")
|
||||
|
||||
:param bytes key: Name to get
|
||||
|
||||
:param bool verify_checksums:
|
||||
If ``True``, all data read from underlying storage will be
|
||||
verified against corresponding checksums.
|
||||
|
||||
:param bool fill_cache:
|
||||
Should the "data block", "index block" or "filter block"
|
||||
read for this iteration be cached in memory?
|
||||
Callers may wish to set this field to ``False`` for bulk scans.
|
||||
|
||||
:param snapshot:
|
||||
If not ``None``, read as of the supplied snapshot
|
||||
(which must belong to the DB that is being read and which must
|
||||
not have been released). Is it ``None`` a implicit snapshot of the
|
||||
state at the beginning of this read operation is used
|
||||
:type snapshot: :py:class:`rocksdb.Snapshot`
|
||||
|
||||
:param string read_tier:
|
||||
Specify if this read request should process data that ALREADY
|
||||
resides on a particular cache. If the required data is not
|
||||
found at the specified cache,
|
||||
then :py:exc:`rocksdb.errors.Incomplete` is raised.
|
||||
|
||||
| Use ``all`` if a fetch from disk is allowed.
|
||||
| Use ``cache`` if only data from cache is allowed.
|
||||
|
||||
:returns: ``None`` if not found, else the value for this key
|
||||
|
||||
.. py:method:: multi_get(keys, verify_checksums=False, fill_cache=True, snapshot=None, read_tier="all")
|
||||
|
||||
:param keys: Keys to fetch
|
||||
:type keys: list of bytes
|
||||
|
||||
For the other params see :py:meth:`rocksdb.DB.get`
|
||||
|
||||
:returns:
|
||||
A ``dict`` where the value is either ``bytes`` or ``None`` if not found
|
||||
|
||||
:raises: If the fetch for a single key fails
|
||||
|
||||
.. note::
|
||||
keys will not be "de-duplicated".
|
||||
Duplicate keys will return duplicate values in order.
|
||||
|
||||
.. py:method:: key_may_exist(key, fetch=False, verify_checksums=False, fill_cache=True, snapshot=None, read_tier="all")
|
||||
|
||||
If the key definitely does not exist in the database, then this method
|
||||
returns ``False``, else ``True``. If the caller wants to obtain value
|
||||
when the key is found in memory, fetch should be set to ``True``.
|
||||
This check is potentially lighter-weight than invoking DB::get().
|
||||
One way to make this lighter weight is to avoid doing any IOs.
|
||||
|
||||
:param bytes key: Key to check
|
||||
:param bool fetch: Obtain also the value if found
|
||||
|
||||
For the other params see :py:meth:`rocksdb.DB.get`
|
||||
|
||||
:returns:
|
||||
* ``(True, None)`` if key is found but value not in memory
|
||||
* ``(True, None)`` if key is found and ``fetch=False``
|
||||
* ``(True, <data>)`` if key is found and value in memory and ``fetch=True``
|

|

|

:param iterate_lower_bound:
|
||||
defines the smallest key at which the backward iterator can return an entry.
|
||||
Once the bound is passed, Valid() will be false. `iterate_lower_bound` is
|
||||
inclusive ie the bound value is a valid entry.
|
||||
If prefix_extractor is not null, the Seek target and `iterate_lower_bound`
|
||||
need to have the same prefix. This is because ordering is not guaranteed
|
||||
outside of prefix domain.
|
||||
:type iterate_lower_bound: bytes
|
||||
|
||||
:param iterate_upper_bound:
|
||||
defines the extent up to which the forward iterator
|
||||
can returns entries. Once the bound is reached, Valid() will be false.
|
||||
"iterate_upper_bound" is exclusive ie the bound value is
|
||||
not a valid entry. If prefix_extractor is not null:
|
||||
1. If auto_prefix_mode = true, iterate_upper_bound will be used
|
||||
to infer whether prefix iterating (e.g. applying prefix bloom filter)
|
||||
can be used within RocksDB. This is done by comparing
|
||||
iterate_upper_bound with the seek key.
|
||||
2. If auto_prefix_mode = false, iterate_upper_bound only takes
|
||||
effect if it shares the same prefix as the seek key. If
|
||||
iterate_upper_bound is outside the prefix of the seek key, then keys
|
||||
returned outside the prefix range will be undefined, just as if
|
||||
iterate_upper_bound = null.
|
||||
If iterate_upper_bound is not null, SeekToLast() will position the iterator
|
||||
at the first key smaller than iterate_upper_bound.

:param include_value: the iterator should include the value in each iteration
|
||||
:type include_value: bool
|

:param fill_cache: Should the "data block"/"index block" read for this iteration be placed in
|
||||
block cache? Callers may wish to set this field to false for bulk scans.
|
||||
This would help not to the change eviction order of existing items in the
|

block cache. Default: true
|
||||
:type fill_cache: bool
|
||||
|
||||
:param bool prefix_same_as_start:
|
||||
Enforce that the iterator only iterates over the same prefix as the seek.
|
||||
This option is effective only for prefix seeks, i.e. prefix_extractor is
|
||||
non-null for the column family and total_order_seek is false. Unlike
|
||||
iterate_upper_bound, prefix_same_as_start only works within a prefix
|
||||
but in both directions. Default: false
|
||||
:type prefix_same_as_start: bool
|
||||
|
||||
:param bool auto_prefix_mode: When true, by default use total_order_seek = true, and RocksDB can
|
||||
selectively enable prefix seek mode if won't generate a different result
|
||||
from total_order_seek, based on seek key, and iterator upper bound.
|
||||
Not supported in ROCKSDB_LITE mode, in the way that even with value true
|

prefix mode is not used. Default: false
|

.. py:method:: snapshot()
|

of the current DB state.
|

:rtype: :py:class:`rocksdb.Snapshot`
|

|

.. py:method:: get_property(prop)
|
||||
|

DB implementations can export properties about their state
|
||||
via this method. If "property" is a valid property understood by this
|
||||
DB implementation, a byte string with its value is returned.
|
||||
Otherwise ``None``
|
||||
|
||||
Valid property names include:
|
||||
|
||||
* ``b"rocksdb.num-files-at-level<N>"``: return the number of files at level <N>,
|
||||
where <N> is an ASCII representation of a level number (e.g. "0").
|
||||
|
||||
* ``b"rocksdb.stats"``: returns a multi-line byte string that describes statistics
|
||||
about the internal operation of the DB.
|
||||
|
||||
* ``b"rocksdb.sstables"``: returns a multi-line byte string that describes all
|
||||
of the sstables that make up the db contents.
|
||||
|
||||
* ``b"rocksdb.num-immutable-mem-table"``: Number of immutable mem tables.
|

* ``b"rocksdb.mem-table-flush-pending"``: Returns ``1`` if mem table flush is pending, otherwise ``0``.
|

* ``b"rocksdb.compaction-pending"``: Returns ``1`` if a compaction is pending, otherweise ``0``.
|

* ``b"rocksdb.background-errors"``: Returns accumulated background errors encountered.
|

* ``b"rocksdb.cur-size-active-mem-table"``: Returns current size of the active memtable.
|
||||
|
||||
.. py:method:: get_live_files_metadata()
|
||||
|
||||
Returns a list of all table files.
|
||||
|
||||
It returns a list of dict's were each dict has the following keys.
|
||||
|
||||
``name``
|
||||
Name of the file
|
||||
|
||||
``level``
|
||||
Level at which this file resides
|
||||
|
||||
``size``
|
||||
File size in bytes
|
||||
|
||||
``smallestkey``
|
||||
Smallest user defined key in the file
|
||||
|
||||
``largestkey``
|
||||
Largest user defined key in the file
|
||||
|

``smallest_seqno``
|

smallest seqno in file
|

``largest_seqno``
|

largest seqno in file
|

.. py:method:: compact_range(begin=None, end=None, ** options)
|
||||
|
||||
Compact the underlying storage for the key range [begin,end].
|
||||
The actual compaction interval might be superset of [begin, end].
|
||||
In particular, deleted and overwritten versions are discarded,
|
||||
and the data is rearranged to reduce the cost of operations
|
||||
needed to access the data.
|
||||
|
||||
This operation should typically only be invoked by users who understand
|
||||
the underlying implementation.
|
||||
|
||||
``begin == None`` is treated as a key before all keys in the database.
|
||||
``end == None`` is treated as a key after all keys in the database.
|
||||
Therefore the following call will compact the entire database: ``db.compact_range()``.
|
||||
|
||||
Note that after the entire database is compacted, all data are pushed
|
||||
down to the last level containing any data. If the total data size
|
||||
after compaction is reduced, that level might not be appropriate for
|
||||
hosting all the files. In this case, client could set change_level
|
||||
to ``True``, to move the files back to the minimum level capable of holding
|
||||
the data set or a given level (specified by non-negative target_level).
|
||||
|
||||
:param bytes begin: Key where to start compaction.
|
||||
If ``None`` start at the beginning of the database.
|
||||
:param bytes end: Key where to end compaction.
|
||||
If ``None`` end at the last key of the database.
|
||||
:param bool change_level: If ``True``, compacted files will be moved to
|
||||
the minimum level capable of holding the data
|
||||
or given level (specified by non-negative target_level).
|
||||
If ``False`` you may end with a bigger level
|
||||
than configured. Default is ``False``.
|
||||
:param int target_level: If change_level is true and target_level have non-negative
|
||||
value, compacted files will be moved to target_level.
|
||||
Default is ``-1``.
|
||||
:param string bottommost_level_compaction:
|
||||
For level based compaction, we can configure if we want to
|
||||
skip/force bottommost level compaction. By default level based
|
||||
compaction will only compact the bottommost level if there is a
|
||||
compaction filter. It can be set to the following values.
|
||||
|
||||
``skip``
|
||||
Skip bottommost level compaction
|
||||
|
||||
``if_compaction_filter``
|
||||
Only compact bottommost level if there is a compaction filter.
|
||||
This is the default.
|
||||
|
||||
``force``
|
||||
Always compact bottommost level
|

WriteBatch
|
||||
==========
|
||||
|
||||
.. py:class:: rocksdb.WriteBatch
|
||||
|
||||
WriteBatch holds a collection of updates to apply atomically to a DB.
|
||||
|
||||
The updates are applied in the order in which they are added
|
||||
to the WriteBatch. For example, the value of "key" will be "v3"
|
||||
after the following batch is written::
|
||||
|
||||
batch = rocksdb.WriteBatch()
|
||||
batch.put(b"key", b"v1")
|
||||
batch.delete(b"key")
|
||||
batch.put(b"key", b"v2")
|
||||
batch.put(b"key", b"v3")
|
||||
|
||||
.. py:method:: __init__(data=None)
|
||||
|
||||
Creates a WriteBatch.
|
||||
|
||||
:param bytes data:
|
||||
A serialized version of a previous WriteBatch. As retrieved
|
||||
from a previous .data() call. If ``None`` a empty WriteBatch is
|
||||
generated
|
||||
|
||||
.. py:method:: put(key, value)
|
||||
|
||||
Store the mapping "key->value" in the database.
|
||||
|
||||
:param bytes key: Name of the entry to store
|
||||
:param bytes value: Data of this entry
|
||||
|
||||
.. py:method:: merge(key, value)
|
||||
|
||||
Merge "value" with the existing value of "key" in the database.
|
||||
|
||||
:param bytes key: Name of the entry to merge
|
||||
:param bytes value: Data to merge
|
||||
|
||||
.. py:method:: delete(key)
|
||||
|
||||
If the database contains a mapping for "key", erase it. Else do nothing.
|
||||
|
||||
:param bytes key: Key to erase
|
||||
|
||||
.. py:method:: clear()
|
||||
|
||||
Clear all updates buffered in this batch.
|
||||
|
||||
.. note::
|
||||
Don't call this method if there is an outstanding iterator.
|
||||
Calling :py:meth:`rocksdb.WriteBatch.clear()` with outstanding
|
||||
iterator, leads to SEGFAULT.
|
||||
|
||||
.. py:method:: data()
|
||||
|
||||
Retrieve the serialized version of this batch.
|
||||
|
||||
:rtype: ``bytes``
|
||||
|
||||
.. py:method:: count()
|
||||
|
||||
Returns the number of updates in the batch
|
||||
|
||||
:rtype: int
|
||||
|
||||
.. py:method:: __iter__()
|
||||
|
||||
Returns an iterator over the current contents of the write batch.
|
||||
|
||||
If you add new items to the batch, they are not visible for this
|
||||
iterator. Create a new one if you need to see them.
|
||||
|
||||
.. note::
|
||||
Calling :py:meth:`rocksdb.WriteBatch.clear()` on the write batch
|
||||
invalidates the iterator. Using a iterator where its corresponding
|
||||
write batch has been cleared, leads to SEGFAULT.
|
||||

WriteBatchIterator
|
||||
==================
|
||||
|
||||
.. py:class:: rocksdb.WriteBatchIterator
|
||||
|
||||
.. py:method:: __iter__()
|
||||
|
||||
Returns self.
|
||||
|
||||
.. py:method:: __next__()
|
||||
|
||||
Returns the next item inside the corresponding write batch.
|
||||
The return value is a tuple of always size three.
|
||||
|
||||
First item (Name of the operation):
|
||||
|
||||
* ``"Put"``
|
||||
* ``"Merge"``
|
||||
* ``"Delete"``
|
||||
|
||||
Second item (key):
|
||||
Key for this operation.
|
||||
|
||||
Third item (value):
|
||||
The value for this operation. Empty for ``"Delete"``.

=========
|

:param opts: Options for this specific database
|

:type opts: :py:class:`rocksdb.Options`
|
||||
|
||||
If a DB cannot be opened, you may attempt to call this method to
|
||||
resurrect as much of the contents of the database as possible.
|

Some data may be lost, so be careful when calling this function
|

Comparator
|

==========
|

|

.. py:class:: rocksdb.interfaces.Comparator
|
||||
|
||||
A Comparator object provides a total order across slices that are
|
||||
used as keys in an sstable or a database. A Comparator implementation
|
||||
must be thread-safe since rocksdb may invoke its methods concurrently
|
||||
from multiple threads.
|

.. py:method:: compare(a, b)

Three-way comparison.

:param bytes a: First field to compare
|
||||
:param bytes b: Second field to compare
|
||||
:returns: * -1 if a < b

* 1 if a > b
|

:rtype: ``int``
|

.. py:method:: name()
|
||||
|

The name of the comparator. Used to check for comparator
|
||||
mismatches (i.e., a DB created with one comparator is
|
||||
accessed using a different comparator).
|
||||
|
||||
The client of this package should switch to a new name whenever
|
||||
the comparator implementation changes in a way that will cause
|
||||
the relative ordering of any two keys to change.
|
||||
|
||||
Names starting with "rocksdb." are reserved and should not be used
|
||||
by any clients of this package.

Merge Operator
|
||||
==============
|
||||
|
||||
Essentially, a MergeOperator specifies the SEMANTICS of a merge, which only
|
||||
client knows. It could be numeric addition, list append, string
|
||||
concatenation, edit data structure, whatever.
|
||||
The library, on the other hand, is concerned with the exercise of this
|
||||
interface, at the right time (during get, iteration, compaction...)
|
||||
|
||||
To use merge, the client needs to provide an object implementing one of
|
||||
the following interfaces:
|
||||
|
||||
* AssociativeMergeOperator - for most simple semantics (always take
|
||||
two values, and merge them into one value, which is then put back
|
||||
into rocksdb).
|
||||
numeric addition and string concatenation are examples.
|
||||
|
||||
* MergeOperator - the generic class for all the more complex operations.
|
||||
One method (FullMerge) to merge a Put/Delete value with a merge operand.
|
||||
Another method (PartialMerge) that merges two operands together.
|
||||
This is especially useful if your key values have a complex structure but
|
||||
you would still like to support client-specific incremental updates.
|
||||
|
||||
AssociativeMergeOperator is simpler to implement.
|
||||
MergeOperator is simply more powerful.
|
||||
|
||||

AssociativeMergeOperator
|

------------------------
|
||||
|
||||
.. py:class:: rocksdb.interfaces.AssociativeMergeOperator
|
||||
|
||||
.. py:method:: merge(key, existing_value, value)
|
||||
|
||||
Gives the client a way to express the read -> modify -> write semantics
|
||||
|
||||
:param bytes key: The key that's associated with this merge operation
|
||||
:param bytes existing_value: The current value in the db.
|
||||
``None`` indicates the key does not exist
|
||||
before this op
|
||||
:param bytes value: The value to update/merge the existing_value with
|
||||
|
||||
:returns: ``True`` and the new value on success.
|
||||
All values passed in will be client-specific values.
|
||||
So if this method returns false, it is because client
|
||||
specified bad data or there was internal corruption.
|
||||
The client should assume that this will be treated as an
|
||||
error by the library.
|
||||
|
||||
:rtype: ``(bool, bytes)``
|
||||
|
||||
.. py:method:: name()
|
||||
|
||||
The name of the MergeOperator. Used to check for MergeOperator mismatches.
|
||||
For example a DB created with one MergeOperator is accessed using a
|
||||
different MergeOperator.
|
||||
|
||||
:rtype: ``bytes``
|
||||
|

MergeOperator
|

-------------
|
||||
|
||||
.. py:class:: rocksdb.interfaces.MergeOperator
|
||||
|
||||
.. py:method:: full_merge(key, existing_value, operand_list)
|
||||
|
||||
Gives the client a way to express the read -> modify -> write semantics
|
||||
|
||||
:param bytes key: The key that's associated with this merge operation.
|
||||
Client could multiplex the merge operator based on it
|
||||
if the key space is partitioned and different subspaces
|
||||
refer to different types of data which have different
|
||||
merge operation semantics
|
||||
|
||||
:param bytes existing_value: The current value in the db.
|
||||
``None`` indicates the key does not exist
|
||||
before this op
|
||||
|
||||
:param operand_list: The sequence of merge operations to apply.
|
||||
:type operand_list: list of bytes
|
||||
|
||||
:returns: ``True`` and the new value on success.
|
||||
All values passed in will be client-specific values.
|
||||
So if this method returns false, it is because client
|
||||
specified bad data or there was internal corruption.
|
||||
The client should assume that this will be treated as an
|
||||
error by the library.
|
||||
|
||||
:rtype: ``(bool, bytes)``
|
||||
|
||||
.. py:method:: partial_merge(key, left_operand, right_operand)
|
||||
|
||||
This function performs merge(left_op, right_op)
|
||||
when both the operands are themselves merge operation types
|
||||
that you would have passed to a DB::Merge() call in the same order.
|
||||
For example DB::Merge(key,left_op), followed by DB::Merge(key,right_op)).
|
||||
|
||||
PartialMerge should combine them into a single merge operation that is
|
||||
returned together with ``True``
|
||||
This new value should be constructed such that a call to
|
||||
DB::Merge(key, new_value) would yield the same result as a call
|
||||
to DB::Merge(key, left_op) followed by DB::Merge(key, right_op).
|
||||
|
||||
If it is impossible or infeasible to combine the two operations,
|
||||
return ``(False, None)`` The library will internally keep track of the
|
||||
operations, and apply them in the correct order once a base-value
|
||||
(a Put/Delete/End-of-Database) is seen.
|
||||

.. note::
|
||||
|

Presently there is no way to differentiate between error/corruption
|
||||
and simply "return false". For now, the client should simply return
|
||||
false in any case it cannot perform partial-merge, regardless of reason.
|
||||
If there is corruption in the data, handle it in the FullMerge() function,
|

and return false there.

.. py:method:: name()
|

different MergeOperator.

FilterPolicy
|
||||
============
|
||||
|
||||
.. py:class:: rocksdb.interfaces.FilterPolicy
|
||||
|
||||
.. py:method:: create_filter(keys)
|
||||
|
||||
Create a bytestring which can act as a filter for keys.
|
||||
|
||||
:param keys: list of keys (potentially with duplicates)
|
||||
that are ordered according to the user supplied
|
||||
comparator.
|

:type keys: list of bytes
|
||||
|
||||
:returns: A filter that summarizes keys
|
||||
:rtype: ``bytes``
|
||||
|

.. py:method:: key_may_match(key, filter)
|
||||
|
||||
Check if the key is maybe in the filter.
|
||||
|
||||
:param bytes key: Key for a single entry inside the database
|
||||
:param bytes filter: Contains the data returned by a preceding call
|
||||
to create_filter on this class
|
||||
:returns: This method must return ``True`` if the key was in the list
|
||||
of keys passed to create_filter().
|
||||
This method may return ``True`` or ``False`` if the key was
|
||||
not on the list, but it should aim to return ``False`` with
|
||||
a high probability.
|
||||
:rtype: ``bool``
|
||||
|
||||
|
||||
.. py:method:: name()
|
||||
|
||||
Return the name of this policy. Note that if the filter encoding
|
||||
changes in an incompatible way, the name returned by this method
|
||||
must be changed. Otherwise, old incompatible filters may be
|
||||
passed to methods of this type.

SliceTransform
|
||||
==============
|
||||
|
||||
.. py:class:: rocksdb.interfaces.SliceTransform
|
||||
|
||||
SliceTransform is currently used to implement the 'prefix-API' of rocksdb.
|
||||
https://github.com/facebook/rocksdb/wiki/Proposal-for-prefix-API
|
||||
|
||||
.. py:method:: transform(src)
|
||||
|
||||
:param bytes src: Full key to extract the prefix from.
|
||||
|
||||
:returns: A tuple of two interges ``(offset, size)``.
|
||||
Where the first integer is the offset within the ``src``
|
||||
and the second the size of the prefix after the offset.
|
||||
Which means the prefix is generted by ``src[offset:offset+size]``
|
||||
|
||||
:rtype: ``(int, int)``
|
||||
|
||||
|
||||
.. py:method:: in_domain(src)

Options creation
|
||||
****************
|
||||
|
||||
Options object
|
||||
==============
|
||||
|
||||
|
||||
.. py:class:: rocksdb.Options
|
||||
|
||||
.. IMPORTANT::
|
||||
|
||||
The default values mentioned here, describe the values of the
|
||||
C++ library only. This wrapper does not set any default value
|
||||
itself. So as soon as the rocksdb developers change a default value
|
||||
this document could be outdated. So if you really depend on a default
|
||||
value, double check it with the according version of the C++ library.
|
||||
|
||||
| Most recent default values should be here
|
||||
| https://github.com/facebook/rocksdb/blob/master/include/rocksdb/options.h
|
||||
| https://github.com/facebook/rocksdb/blob/master/util/options.cc
|
||||
|
||||
.. py:method:: __init__(**kwargs)
|
||||
|
||||
All options mentioned below can also be passed as keyword-arguments in
|
||||
the constructor. For example::
|
||||
|
||||
import rocksdb
|
||||
|
||||
opts = rocksdb.Options(create_if_missing=True)
|
||||
# is the same as
|
||||
opts = rocksdb.Options()
|
||||
opts.create_if_missing = True
|
||||
|
||||
|
||||
.. py:attribute:: create_if_missing
|
||||
|
||||
If ``True``, the database will be created if it is missing.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``False``
|
||||
|
||||
.. py:attribute:: error_if_exists
|
||||
|
||||
If ``True``, an error is raised if the database already exists.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``False``
|
||||
|
||||
|
||||
.. py:attribute:: paranoid_checks
|
||||
|
||||
If ``True``, the implementation will do aggressive checking of the
|
||||
data it is processing and will stop early if it detects any
|
||||
errors. This may have unforeseen ramifications: for example, a
|
||||
corruption of one DB entry may cause a large number of entries to
|
||||
become unreadable or for the entire DB to become unopenable.
|
||||
If any of the writes to the database fails (Put, Delete, Merge, Write),
|
||||
the database will switch to read-only mode and fail all other
|
||||
Write operations.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``True``
|
||||
|
||||
.. py:attribute:: write_buffer_size
|
||||
|
||||
Amount of data to build up in memory (backed by an unsorted log
|
||||
on disk) before converting to a sorted on-disk file.
|
||||
|
||||
Larger values increase performance, especially during bulk loads.
|
||||
Up to max_write_buffer_number write buffers may be held in memory
|
||||
at the same time, so you may wish to adjust this parameter to control
|
||||
memory usage. Also, a larger write buffer will result in a longer recovery
|
||||
time the next time the database is opened.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``4194304``
|
||||
|
||||
.. py:attribute:: max_write_buffer_number
|
||||
|
||||
The maximum number of write buffers that are built up in memory.
|
||||
The default is 2, so that when 1 write buffer is being flushed to
|
||||
storage, new writes can continue to the other write buffer.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``2``
|
||||
|
||||
.. py:attribute:: min_write_buffer_number_to_merge
|
||||
|
||||
The minimum number of write buffers that will be merged together
|
||||
before writing to storage. If set to 1, then
|
||||
all write buffers are fushed to L0 as individual files and this increases
|
||||
read amplification because a get request has to check in all of these
|
||||
files. Also, an in-memory merge may result in writing lesser
|
||||
data to storage if there are duplicate records in each of these
|
||||
individual write buffers.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``1``
|
||||
|
||||
.. py:attribute:: max_open_files
|
||||
|
||||
Number of open files that can be used by the DB. You may need to
|
||||
increase this if your database has a large working set. Value -1 means
|
||||
files opened are always kept open. You can estimate number of
|
||||
files based on target_file_size_base and target_file_size_multiplier
|
||||
for level-based compaction.
|
||||
For universal-style compaction, you can usually set it to -1.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``5000``
|
||||
|
||||
.. py:attribute:: compression
|
||||
|
||||
Compress blocks using the specified compression algorithm.
|
||||
This parameter can be changed dynamically.
|
||||
|
||||
| *Type:* Member of :py:class:`rocksdb.CompressionType`
|
||||
| *Default:* :py:attr:`rocksdb.CompressionType.snappy_compression`
|
||||
|
||||
.. py:attribute:: num_levels
|
||||
|
||||
Number of levels for this database
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``7``
|
||||
|
||||
|
||||
.. py:attribute:: level0_file_num_compaction_trigger
|
||||
|
||||
Number of files to trigger level-0 compaction. A value <0 means that
|
||||
level-0 compaction will not be triggered by number of files at all.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``4``
|
||||
|
||||
.. py:attribute:: level0_slowdown_writes_trigger
|
||||
|
||||
Soft limit on number of level-0 files. We start slowing down writes at this
|
||||
point. A value <0 means that no writing slow down will be triggered by
|
||||
number of files in level-0.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``20``
|
||||
|
||||
.. py:attribute:: level0_stop_writes_trigger
|
||||
|
||||
Maximum number of level-0 files. We stop writes at this point.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``24``
|
||||
|
||||
.. py:attribute:: max_mem_compaction_level
|
||||
|
||||
Maximum level to which a new compacted memtable is pushed if it
|
||||
does not create overlap. We try to push to level 2 to avoid the
|
||||
relatively expensive level 0=>1 compactions and to avoid some
|
||||
expensive manifest file operations. We do not push all the way to
|
||||
the largest level since that can generate a lot of wasted disk
|
||||
space if the same key space is being repeatedly overwritten.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``2``
|
||||
|
||||
|
||||
.. py:attribute:: target_file_size_base
|
||||
|
||||
| Target file size for compaction.
|
||||
| target_file_size_base is per-file size for level-1.
|
||||
| Target file size for level L can be calculated by
|
||||
| target_file_size_base * (target_file_size_multiplier ^ (L-1)).
|
||||
|
||||
For example, if target_file_size_base is 2MB and
|
||||
target_file_size_multiplier is 10, then each file on level-1 will
|
||||
be 2MB, and each file on level 2 will be 20MB,
|
||||
and each file on level-3 will be 200MB.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``2097152``
|
||||
|
||||
.. py:attribute:: target_file_size_multiplier
|
||||
|
||||
| by default target_file_size_multiplier is 1, which means
|
||||
| by default files in different levels will have similar size.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``1``
|
||||
|
||||
.. py:attribute:: max_bytes_for_level_base
|
||||
|
||||
Control maximum total data size for a level.
|
||||
*max_bytes_for_level_base* is the max total for level-1.
|
||||
Maximum number of bytes for level L can be calculated as
|
||||
(*max_bytes_for_level_base*) * (*max_bytes_for_level_multiplier* ^ (L-1))
|
||||
For example, if *max_bytes_for_level_base* is 20MB, and if
|
||||
*max_bytes_for_level_multiplier* is 10, total data size for level-1
|
||||
will be 20MB, total file size for level-2 will be 200MB,
|
||||
and total file size for level-3 will be 2GB.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``10485760``
|
||||
|
||||
.. py:attribute:: max_bytes_for_level_multiplier
|
||||
|
||||
See :py:attr:`max_bytes_for_level_base`
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``10``
|
||||
|
||||
.. py:attribute:: max_bytes_for_level_multiplier_additional
|
||||
|
||||
Different max-size multipliers for different levels.
|
||||
These are multiplied by max_bytes_for_level_multiplier to arrive
|
||||
at the max-size of each level.
|
||||
|
||||
| *Type:* ``[int]``
|
||||
| *Default:* ``[1, 1, 1, 1, 1, 1, 1]``
|
||||
|
||||
.. py:attribute:: max_compaction_bytes
|
||||
|
||||
We try to limit number of bytes in one compaction to be lower than this
|
||||
threshold. But it's not guaranteed.
|
||||
Value 0 will be sanitized.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``target_file_size_base * 25``
|
||||
|
||||
.. py:attribute:: use_fsync
|
||||
|
||||
If true, then every store to stable storage will issue a fsync.
|
||||
If false, then every store to stable storage will issue a fdatasync.
|
||||
This parameter should be set to true while storing data to
|
||||
filesystem like ext3 that can lose files after a reboot.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``False``
|
||||
|
||||
.. py:attribute:: db_log_dir
|
||||
|
||||
This specifies the info LOG dir.
|
||||
If it is empty, the log files will be in the same dir as data.
|
||||
If it is non empty, the log files will be in the specified dir,
|
||||
and the db data dir's absolute path will be used as the log file
|
||||
name's prefix.
|
||||
|
||||
| *Type:* ``unicode``
|
||||
| *Default:* ``""``
|
||||
|
||||
.. py:attribute:: wal_dir
|
||||
|
||||
This specifies the absolute dir path for write-ahead logs (WAL).
|
||||
If it is empty, the log files will be in the same dir as data,
|
||||
dbname is used as the data dir by default.
|
||||
If it is non empty, the log files will be in kept the specified dir.
|
||||
When destroying the db, all log files in wal_dir and the dir itself is deleted
|
||||
|
||||
| *Type:* ``unicode``
|
||||
| *Default:* ``""``
|
||||
|
||||
.. py:attribute:: delete_obsolete_files_period_micros
|
||||
|
||||
The periodicity when obsolete files get deleted. The default
|
||||
value is 6 hours. The files that get out of scope by compaction
|
||||
process will still get automatically delete on every compaction,
|
||||
regardless of this setting
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``21600000000``
|
||||
|
||||
.. py:attribute:: max_background_compactions
|
||||
|
||||
Maximum number of concurrent background jobs, submitted to
|
||||
the default LOW priority thread pool
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``1``
|
||||
|
||||
.. py:attribute:: max_background_flushes
|
||||
|
||||
Maximum number of concurrent background memtable flush jobs, submitted to
|
||||
the HIGH priority thread pool.
|
||||
By default, all background jobs (major compaction and memtable flush) go
|
||||
to the LOW priority pool. If this option is set to a positive number,
|
||||
memtable flush jobs will be submitted to the HIGH priority pool.
|
||||
It is important when the same Env is shared by multiple db instances.
|
||||
Without a separate pool, long running major compaction jobs could
|
||||
potentially block memtable flush jobs of other db instances, leading to
|
||||
unnecessary Put stalls.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``1``
|
||||
|
||||
.. py:attribute:: max_log_file_size
|
||||
|
||||
Specify the maximal size of the info log file. If the log file
|
||||
is larger than `max_log_file_size`, a new info log file will
|
||||
be created.
|
||||
If max_log_file_size == 0, all logs will be written to one
|
||||
log file.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``0``
|
||||
|
||||
.. py:attribute:: log_file_time_to_roll
|
||||
|
||||
Time for the info log file to roll (in seconds).
|
||||
If specified with non-zero value, log file will be rolled
|
||||
if it has been active longer than `log_file_time_to_roll`.
|
||||
A value of ``0`` means disabled.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``0``
|
||||
|
||||
.. py:attribute:: keep_log_file_num
|
||||
|
||||
Maximal info log files to be kept.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``1000``
|
||||
|
||||
.. py:attribute:: soft_rate_limit
|
||||
|
||||
Puts are delayed 0-1 ms when any level has a compaction score that exceeds
|
||||
soft_rate_limit. This is ignored when == 0.0.
|
||||
CONSTRAINT: soft_rate_limit <= hard_rate_limit. If this constraint does not
|
||||
hold, RocksDB will set soft_rate_limit = hard_rate_limit.
|
||||
A value of ``0`` means disabled.
|
||||
|
||||
| *Type:* ``float``
|
||||
| *Default:* ``0``
|
||||
|
||||
.. py:attribute:: hard_rate_limit
|
||||
|
||||
Puts are delayed 1ms at a time when any level has a compaction score that
|
||||
exceeds hard_rate_limit. This is ignored when <= 1.0.
|
||||
A value fo ``0`` means disabled.
|
||||
|
||||
| *Type:* ``float``
|
||||
| *Default:* ``0``
|
||||
|
||||
.. py:attribute:: rate_limit_delay_max_milliseconds
|
||||
|
||||
Max time a put will be stalled when hard_rate_limit is enforced. If 0, then
|
||||
there is no limit.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``1000``
|
||||
|
||||
.. py:attribute:: max_manifest_file_size
|
||||
|
||||
manifest file is rolled over on reaching this limit.
|
||||
The older manifest file be deleted.
|
||||
The default value is MAX_INT so that roll-over does not take place.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``(2**64) - 1``
|
||||
|
||||
.. py:attribute:: table_cache_numshardbits
|
||||
|
||||
Number of shards used for table cache.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``4``
|
||||
|
||||
.. py:attribute:: arena_block_size
|
||||
|
||||
size of one block in arena memory allocation.
|
||||
If <= 0, a proper value is automatically calculated (usually 1/10 of
|
||||
writer_buffer_size).
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``0``
|
||||
|
||||
.. py:attribute:: disable_auto_compactions
|
||||
|
||||
Disable automatic compactions. Manual compactions can still
|
||||
be issued on this database.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``False``
|
||||
|
||||
.. py:attribute:: wal_ttl_seconds, wal_size_limit_mb
|
||||
|
||||
The following two fields affect how archived logs will be deleted.
|
||||
|
||||
1. If both set to 0, logs will be deleted asap and will not get into
|
||||
the archive.
|
||||
2. If wal_ttl_seconds is 0 and wal_size_limit_mb is not 0,
|
||||
WAL files will be checked every 10 min and if total size is greater
|
||||
then wal_size_limit_mb, they will be deleted starting with the
|
||||
earliest until size_limit is met. All empty files will be deleted.
|
||||
3. If wal_ttl_seconds is not 0 and wal_size_limit_mb is 0, then
|
||||
WAL files will be checked every wal_ttl_secondsi / 2 and those that
|
||||
are older than wal_ttl_seconds will be deleted.
|
||||
4. If both are not 0, WAL files will be checked every 10 min and both
|
||||
checks will be performed with ttl being first.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``0``
|
||||
|
||||
.. py:attribute:: manifest_preallocation_size
|
||||
|
||||
Number of bytes to preallocate (via fallocate) the manifest
|
||||
files. Default is 4mb, which is reasonable to reduce random IO
|
||||
as well as prevent overallocation for mounts that preallocate
|
||||

|
||||
access pattern is random, when a sst file is opened.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``True``
|
||||
|
||||
.. py:attribute:: use_adaptive_mutex
|
||||
|
||||
Use adaptive mutex, which spins in the user space before resorting
|
||||
to kernel. This could reduce context switch when the mutex is not
|
||||
heavily contended. However, if the mutex is hot, we could end up
|
||||
wasting spin time.
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``False``
|
||||
|

|
||||
|
||||
|
||||
.. py:attribute:: compaction_style
|
||||
|
||||
The compaction style. Could be set to ``"level"`` to use level-style
|
||||
compaction. For universal-style compaction use ``"universal"``. For
|
||||
FIFO compaction use ``"fifo"``. If no compaction style use ``"none"``.
|
||||
|
||||
| *Type:* ``string``
|
||||
| *Default:* ``level``
|
||||
|
||||
.. py:attribute:: compaction_pri
|
||||
|
||||
If level compaction_style = kCompactionStyleLevel, for each level,
|
||||
which files are prioritized to be picked to compact.
|
||||
|
||||
| *Type:* Member of :py:class:`rocksdb.CompactionPri`
|
||||
| *Default:* :py:attr:`rocksdb.CompactionPri.kByCompensatedSize`
|
||||
|
||||
.. py:attribute:: compaction_options_universal
|
||||
|
||||
Options to use for universal-style compaction. They make only sense if
|
||||
:py:attr:`rocksdb.Options.compaction_style` is set to ``"universal"``.
|
||||
|
||||
It is a dict with the following keys.
|
||||
|
||||
* ``size_ratio``:
|
||||
Percentage flexibilty while comparing file size.
|
||||
If the candidate file(s) size is 1% smaller than the next file's size,
|
||||
then include next file into this candidate set.
|
||||
Default: ``1``
|
||||
|
||||
* ``min_merge_width``:
|
||||
The minimum number of files in a single compaction run.
|
||||
Default: ``2``
|
||||
|
||||
* ``max_merge_width``:
|
||||
The maximum number of files in a single compaction run.
|
||||
Default: ``UINT_MAX``
|
||||
|
||||
* ``max_size_amplification_percent``:
|
||||
The size amplification is defined as the amount (in percentage) of
|
||||
additional storage needed to store a single byte of data in the database.
|
||||
For example, a size amplification of 2% means that a database that
|
||||
contains 100 bytes of user-data may occupy upto 102 bytes of
|
||||
physical storage. By this definition, a fully compacted database has
|
||||
a size amplification of 0%. Rocksdb uses the following heuristic
|
||||
to calculate size amplification: it assumes that all files excluding
|
||||
the earliest file contribute to the size amplification.
|
||||
Default: ``200``, which means that a 100 byte database could require upto
|
||||
300 bytes of storage.
|
||||
|
||||
* ``compression_size_percent``:
|
||||
If this option is set to be -1 (the default value), all the output
|
||||
files will follow compression type specified.
|
||||
|
||||
If this option is not negative, we will try to make sure compressed
|
||||
size is just above this value. In normal cases, at least this
|
||||
percentage of data will be compressed.
|
||||
|
||||
When we are compacting to a new file, here is the criteria whether
|
||||
it needs to be compressed: assuming here are the list of files sorted
|
||||
by generation time: ``A1...An B1...Bm C1...Ct``
|
||||
where ``A1`` is the newest and ``Ct`` is the oldest, and we are going
|
||||
to compact ``B1...Bm``, we calculate the total size of all the files
|
||||
as total_size, as well as the total size of ``C1...Ct`` as
|
||||
``total_C``, the compaction output file will be compressed if
|
||||
``total_C / total_size < this percentage``.
|
||||
Default: -1
|
||||
|
||||
* ``stop_style``:
|
||||
The algorithm used to stop picking files into a single compaction.
|
||||
Can be either ``"similar_size"`` or ``"total_size"``.
|
||||
|
||||
* ``similar_size``: Pick files of similar size.
|
||||
* ``total_size``: Total size of picked files is greater than next file.
|
||||
|
||||
Default: ``"total_size"``
|
||||
|
||||
For setting options, just assign a dict with the fields to set.
|
||||
It is allowed to omit keys in this dict. Missing keys are just not set
|
||||
to the underlying options object.
|
||||
|
||||
This example just changes the stop_style and leaves the other options
|
||||
untouched. ::
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.compaction_options_universal = {'stop_style': 'similar_size'}
|
||||
|
||||
|
||||
.. py:attribute:: max_sequential_skip_in_iterations
|
||||
|
||||
An iteration->Next() sequentially skips over keys with the same
|
||||
user-key unless this option is set. This number specifies the number
|
||||
of keys (with the same userkey) that will be sequentially
|
||||
skipped before a reseek is issued.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``8``
|
||||
|
||||
.. py:attribute:: memtable_factory
|
||||
|
||||
This is a factory that provides MemTableRep objects.
|
||||
Right now you can assing instances of the following classes.
|
||||
|
||||
* :py:class:`rocksdb.VectorMemtableFactory`
|
||||
* :py:class:`rocksdb.SkipListMemtableFactory`
|
||||
* :py:class:`rocksdb.HashSkipListMemtableFactory`
|
||||
* :py:class:`rocksdb.HashLinkListMemtableFactory`
|
||||
|
||||
*Default:* :py:class:`rocksdb.SkipListMemtableFactory`
|
||||
|
||||
.. py:attribute:: table_factory
|
||||
|
||||
Factory for the files forming the persisten data storage.
|
||||
Sometimes they are also named SST-Files. Right now you can assign
|
||||
instances of the following classes.
|
||||
|
||||
* :py:class:`rocksdb.BlockBasedTableFactory`
|
||||
* :py:class:`rocksdb.PlainTableFactory`
|
||||
* :py:class:`rocksdb.TotalOrderPlainTableFactory`
|
||||
|
||||
*Default:* :py:class:`rocksdb.BlockBasedTableFactory`
|
||||
|
||||
.. py:attribute:: inplace_update_support
|
||||
|
||||
Allows thread-safe inplace updates. Requires Updates if
|
||||
|
||||
* key exists in current memtable
|
||||
* new sizeof(new_value) <= sizeof(old_value)
|
||||
* old_value for that key is a put i.e. kTypeValue
|
||||
|
||||
| *Type:* ``bool``
|
||||
| *Default:* ``False``
|
||||
|
||||
.. py:attribute:: inplace_update_num_locks
|
||||
|
||||
| Number of locks used for inplace update.
|
||||
| Default: 10000, if inplace_update_support = true, else 0.
|
||||
|
||||
| *Type:* ``int``
|
||||
| *Default:* ``10000``
|
||||
|
||||
.. py:attribute:: comparator
|
||||
|
||||
Comparator used to define the order of keys in the table.
|
||||
A python comparator must implement the :py:class:`rocksdb.interfaces.Comparator`
|
||||
interface.
|
||||
|
||||
*Requires*: The client must ensure that the comparator supplied
|
||||
here has the same name and orders keys *exactly* the same as the
|
||||
comparator provided to previous open calls on the same DB.
|
||||
|
||||
*Default:* :py:class:`rocksdb.BytewiseComparator`
|
||||
|
||||
.. py:attribute:: merge_operator
|
||||
|
||||
The client must provide a merge operator if Merge operation
|
||||
needs to be accessed. Calling Merge on a DB without a merge operator
|
||||
would result in :py:exc:`rocksdb.errors.NotSupported`. The client must
|
||||
ensure that the merge operator supplied here has the same name and
|
||||
*exactly* the same semantics as the merge operator provided to
|
||||
previous open calls on the same DB. The only exception is reserved
|
||||
for upgrade, where a DB previously without a merge operator is
|
||||
introduced to Merge operation for the first time. It's necessary to
|
||||
specify a merge operator when openning the DB in this case.
|
||||
|
||||
A python merge operator must implement the
|
||||
:py:class:`rocksdb.interfaces.MergeOperator` or
|
||||
:py:class:`rocksdb.interfaces.AssociativeMergeOperator`
|
||||
interface.
|
||||
|
||||
*Default:* ``None``
|
||||
|
||||
.. py:attribute:: prefix_extractor
|
||||
|
||||
If not ``None``, use the specified function to determine the
|
||||
prefixes for keys. These prefixes will be placed in the filter.
|
||||
Depending on the workload, this can reduce the number of read-IOP
|
||||
cost for scans when a prefix is passed to the calls generating an
|
||||
iterator (:py:meth:`rocksdb.DB.iterkeys` ...).
|
||||
|
||||
A python prefix_extractor must implement the
|
||||
:py:class:`rocksdb.interfaces.SliceTransform` interface
|
||||
|
||||
For prefix filtering to work properly, "prefix_extractor" and "comparator"
|
||||
must be such that the following properties hold:
|
||||
|
||||
1. ``key.starts_with(prefix(key))``
|
||||
2. ``compare(prefix(key), key) <= 0``
|
||||
3. ``If compare(k1, k2) <= 0, then compare(prefix(k1), prefix(k2)) <= 0``
|
||||
4. ``prefix(prefix(key)) == prefix(key)``
|
||||
|
||||
*Default:* ``None``
|
||||
|
||||
.. py:attribute:: row_cache
|
||||
|
||||
A global cache for table-level rows. If ``None`` this cache is not used.
|
||||
Otherwise it must be an instance of :py:class:`rocksdb.LRUCache`
|
||||
|
||||
*Default:* ``None``
|
||||
|
||||

BytewiseComparator
|
||||
==================
|
||||
|
||||
.. py:class:: rocksdb.BytewiseComparator
|
||||
|
||||
Wraps the rocksdb Bytewise Comparator, it uses lexicographic byte-wise
|

=================
|
||||
|

Wraps the rocksdb BloomFilter Policy
|
||||
|

.. py:method:: __init__(bits_per_key)
|
||||
|
||||
:param int bits_per_key:
|
||||
Specifies the approximately number of bits per key.
|
||||
A good value for bits_per_key is 10, which yields a filter with
|

TableFactories
|
||||
==============
|
||||
|
||||
Currently RocksDB supports two types of tables: plain table and block-based table.
|
||||
Instances of this classes can assigned to :py:attr:`rocksdb.Options.table_factory`
|
||||
|
||||
* *Block-based table:* This is the default table type that RocksDB inherited from
|
||||
LevelDB. It was designed for storing data in hard disk or flash device.
|
||||
|
||||
* *Plain table:* It is one of RocksDB's SST file format optimized
|
||||
for low query latency on pure-memory or really low-latency media.
|
||||
|
||||
Tutorial of rocksdb table formats is available here:
|
||||
https://github.com/facebook/rocksdb/wiki/A-Tutorial-of-RocksDB-SST-formats
|
||||
|
||||
.. py:class:: rocksdb.BlockBasedTableFactory
|
||||
|
||||
Wraps BlockBasedTableFactory of RocksDB.
|
||||
|
||||
.. py:method:: __init__(index_type='binary_search', hash_index_allow_collision=True, checksum='crc32', block_cache, block_cache_compressed, filter_policy=None, no_block_cache=False, block_size=None, block_size_deviation=None, block_restart_interval=None, whole_key_filtering=None):
|
||||
|
||||
|
||||
:param string index_type:
|
||||
* ``binary_search`` a space efficient index block that is optimized
|
||||
for binary-search-based index.
|
||||
* ``hash_search`` the hash index. If enabled, will do hash lookup
|
||||
when `Options.prefix_extractor` is provided.
|
||||
|
||||
:param bool hash_index_allow_collision:
|
||||
Influence the behavior when ``hash_search`` is used.
|
||||
If ``False``, stores a precise prefix to block range mapping.
|
||||
If ``True``, does not store prefix and allows prefix hash collision
|
||||
(less memory consumption)
|
||||
|
||||
:param string checksum:
|
||||
Use the specified checksum type. Newly created table files will be
|
||||
protected with this checksum type. Old table files will still be readable,
|
||||
even though they have different checksum type.
|
||||
Can be either ``crc32`` or ``xxhash``.
|
||||
|
||||
:param block_cache:
|
||||
Control over blocks (user data is stored in a set of blocks, and
|
||||
a block is the unit of reading from disk).
|
||||
|
||||
If ``None``, rocksdb will automatically create and use an 8MB internal cache.
|
||||
If not ``None`` use the specified cache for blocks. In that case it must
|
||||
be an instance of :py:class:`rocksdb.LRUCache`
|
||||
|
||||
:param block_cache_compressed:
|
||||
If ``None``, rocksdb will not use a compressed block cache.
|
||||
If not ``None`` use the specified cache for compressed blocks. In that
|
||||
case it must be an instance of :py:class:`rocksdb.LRUCache`
|
||||
|
||||
:param filter_policy:
|
||||
If not ``None`` use the specified filter policy to reduce disk reads.
|
||||
A python filter policy must implement the
|
||||
:py:class:`rocksdb.interfaces.FilterPolicy` interface.
|
||||
Recommended is a instance of :py:class:`rocksdb.BloomFilterPolicy`
|
||||
|
||||
:param bool no_block_cache:
|
||||
Disable block cache. If this is set to true,
|
||||
then no block cache should be used, and the block_cache should
|
||||
point to ``None``
|
||||
|
||||
:param int block_size:
|
||||
If set to ``None`` the rocksdb default of ``4096`` is used.
|
||||
Approximate size of user data packed per block. Note that the
|
||||
block size specified here corresponds to uncompressed data. The
|
||||
actual size of the unit read from disk may be smaller if
|
||||
compression is enabled. This parameter can be changed dynamically.
|
||||
|
||||
:param int block_size_deviation:
|
||||
If set to ``None`` the rocksdb default of ``10`` is used.
|
||||
This is used to close a block before it reaches the configured
|
||||
'block_size'. If the percentage of free space in the current block is less
|
||||
than this specified number and adding a new record to the block will
|
||||
exceed the configured block size, then this block will be closed and the
|
||||
new record will be written to the next block.
|
||||
|
||||
:param int block_restart_interval:
|
||||
If set to ``None`` the rocksdb default of ``16`` is used.
|
||||
Number of keys between restart points for delta encoding of keys.
|
||||
This parameter can be changed dynamically. Most clients should
|
||||
leave this parameter alone.
|
||||
|
||||
:param bool whole_key_filtering:
|
||||
If set to ``None`` the rocksdb default of ``True`` is used.
|
||||
If ``True``, place whole keys in the filter (not just prefixes).
|
||||
This must generally be true for gets to be efficient.
|
||||
|
||||
.. py:class:: rocksdb.PlainTableFactory
|
||||
|
||||
Plain Table with prefix-only seek. It wraps rocksdb PlainTableFactory.
|
||||
|
||||
For this factory, you need to set :py:attr:`rocksdb.Options.prefix_extractor`
|
||||
properly to make it work. Look-up will start with prefix hash lookup for
|
||||
key prefix. Inside the hash bucket found, a binary search is executed for
|
||||
hash conflicts. Finally, a linear search is used.
|
||||
|
||||
.. py:method:: __init__(user_key_len=0, bloom_bits_per_key=10, hash_table_ratio=0.75, index_sparseness=10, huge_page_tlb_size=0, encoding_type='plain', full_scan_mode=False, store_index_in_file=False)
|
||||
|
||||
:param int user_key_len:
|
||||
Plain table has optimization for fix-sized keys, which can be
|
||||
specified via user_key_len.
|
||||
Alternatively, you can pass `0` if your keys have variable lengths.
|
||||
|
||||
:param int bloom_bits_per_key:
|
||||
The number of bits used for bloom filer per prefix.
|
||||
You may disable it by passing `0`.
|
||||
|
||||
:param float hash_table_ratio:
|
||||
The desired utilization of the hash table used for prefix hashing.
|
||||
hash_table_ratio = number of prefixes / #buckets in the hash table.
|
||||
|
||||
:param int index_sparseness:
|
||||
Inside each prefix, need to build one index record for how
|
||||
many keys for binary search inside each hash bucket.
|
||||
For encoding type ``prefix``, the value will be used when
|
||||
writing to determine an interval to rewrite the full key.
|
||||
It will also be used as a suggestion and satisfied when possible.
|
||||
|
||||
:param int huge_page_tlb_size:
|
||||
If <=0, allocate hash indexes and blooms from malloc.
|
||||
Otherwise from huge page TLB.
|
||||
The user needs to reserve huge pages for it to be allocated, like:
|
||||
``sysctl -w vm.nr_hugepages=20``
|
||||
See linux doc Documentation/vm/hugetlbpage.txt
|
||||
|
||||
:param string encoding_type:
|
||||
How to encode the keys. The value will determine how to encode keys
|
||||
when writing to a new SST file. This value will be stored
|
||||
inside the SST file which will be used when reading from the
|
||||
file, which makes it possible for users to choose different
|
||||
encoding type when reopening a DB. Files with different
|
||||
encoding types can co-exist in the same DB and can be read.
|
||||
|
||||
* ``plain``: Always write full keys without any special encoding.
|
||||
* ``prefix``: Find opportunity to write the same prefix once for multiple rows.
|
||||
In some cases, when a key follows a previous key with the same prefix,
|
||||
instead of writing out the full key, it just writes out the size of the
|
||||
shared prefix, as well as other bytes, to save some bytes.
|
||||
|
||||
When using this option, the user is required to use the same prefix
|
||||
extractor to make sure the same prefix will be extracted from the same key.
|
||||
The Name() value of the prefix extractor will be stored in the file.
|
||||
When reopening the file, the name of the options.prefix_extractor given
|
||||
will be bitwise compared to the prefix extractors stored in the file.
|
||||
An error will be returned if the two don't match.
|
||||
|
||||
:param bool full_scan_mode:
|
||||
Mode for reading the whole file one record by one without using the index.
|
||||
|
||||
:param bool store_index_in_file:
|
||||
Compute plain table index and bloom filter during file building
|
||||
and store it in file. When reading file, index will be mmaped
|
||||
instead of recomputation.

MemtableFactories
|
||||
=================
|
||||
|
||||
RocksDB has different classes to represent the in-memory buffer for the current
|
||||
operations. You have to assing instances of the following classes to
|
||||
:py:attr:`rocksdb.Options.memtable_factory`.
|
||||
This page has a comparison the most popular ones.
|
||||
https://github.com/facebook/rocksdb/wiki/Hash-based-memtable-implementations
|
||||
|
||||
.. py:class:: rocksdb.VectorMemtableFactory
|
||||
|
||||
This creates MemTableReps that are backed by an std::vector.
|
||||
On iteration, the vector is sorted. This is useful for workloads where
|
||||
iteration is very rare and writes are generally not issued after reads begin.
|
||||
|
||||
.. py:method:: __init__(count=0)
|
||||
|
||||
:param int count:
|
||||
Passed to the constructor of the underlying std::vector of each
|
||||
VectorRep. On initialization, the underlying array will be at
|
||||
least count bytes reserved for usage.
|
||||
|
||||
.. py:class:: rocksdb.SkipListMemtableFactory
|
||||
|
||||
This uses a skip list to store keys.
|
||||
|
||||
.. py:method:: __init__()
|
||||
|
||||
.. py:class:: rocksdb.HashSkipListMemtableFactory
|
||||
|
||||
This class contains a fixed array of buckets, each pointing
|
||||
to a skiplist (null if the bucket is empty).
|
||||
|
||||
.. note::
|
||||
|
||||
:py:attr:`rocksdb.Options.prefix_extractor` must be set, otherwise
|
||||
rocksdb fails back to skip-list.
|
||||
|
||||
.. py:method:: __init__(bucket_count = 1000000, skiplist_height = 4, skiplist_branching_factor = 4)
|
||||
|
||||
:param int bucket_count: number of fixed array buckets
|
||||
:param int skiplist_height: the max height of the skiplist
|
||||
:param int skiplist_branching_factor:
|
||||
probabilistic size ratio between adjacent link lists in the skiplist
|
||||
|
||||
.. py:class:: rocksdb.HashLinkListMemtableFactory
|
||||
|
||||
The factory is to create memtables with a hashed linked list.
|
||||
It contains a fixed array of buckets, each pointing to a sorted single
|
||||
linked list (null if the bucket is empty).
|
||||
|
||||
.. note::
|
||||
|
||||
:py:attr:`rocksdb.Options.prefix_extractor` must be set, otherwise
|
||||
rocksdb fails back to skip-list.
|
||||
|
||||
|
||||
.. py:method:: __init__(bucket_count=50000)
|
||||
|
||||
:param int bucket: number of fixed array buckets

Basic Usage of python-rocksdb
|
||||
*****************************
|
||||
|
||||
Open
|
||||
====
|
||||
|
||||
The most basic open call is ::
|
||||
|
||||
import rocksdb
|
||||
|
||||
db = rocksdb.DB("test.db", rocksdb.Options(create_if_missing=True))
|
||||
|
||||
A more production ready open can look like this ::
|
||||
|
||||
import rocksdb
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.create_if_missing = True
|
||||
opts.max_open_files = 300000
|
||||
opts.write_buffer_size = 67108864
|
||||
opts.max_write_buffer_number = 3
|
||||
opts.target_file_size_base = 67108864
|
||||
|
||||
opts.table_factory = rocksdb.BlockBasedTableFactory(
|
||||
filter_policy=rocksdb.BloomFilterPolicy(10),
|
||||
block_cache=rocksdb.LRUCache(2 * (1024 ** 3)),
|
||||
block_cache_compressed=rocksdb.LRUCache(500 * (1024 ** 2)))
|
||||
|
||||
db = rocksdb.DB("test.db", opts)
|
||||
|
||||
It assings a cache of 2.5G, uses a bloom filter for faster lookups and keeps
|
||||
more data (64 MB) in memory before writting a .sst file.
|
||||
|
||||
About Bytes And Unicode
|
||||
=======================
|
||||
|
||||
RocksDB stores all data as uninterpreted *byte strings*.
|
||||
pyrocksdb behaves the same and uses nearly everywhere byte strings too.
|
||||
In python2 this is the ``str`` type. In python3 the ``bytes`` type.
|
||||
Since the default string type for string literals differs between python 2 and 3,
|
||||
it is strongly recommended to use an explicit ``b`` prefix for all byte string
|
||||
literals in both python2 and python3 code.
|
||||
For example ``b'this is a byte string'``. This avoids ambiguity and ensures
|
||||
that your code keeps working as intended if you switch between python2 and python3.
|
||||
|
||||
The only place where you can pass unicode objects are filesytem paths like
|
||||
|
||||
* Directory name of the database itself :py:meth:`rocksdb.DB.__init__`
|
||||
|
||||
* :py:attr:`rocksdb.Options.wal_dir`
|
||||
|
||||
* :py:attr:`rocksdb.Options.db_log_dir`
|
||||
|
||||
To encode this path name, `sys.getfilesystemencoding()` encoding is used.
|
||||
|
||||
Access
|
||||
======
|
||||
|
||||
Store, Get, Delete is straight forward ::
|
||||
|
||||
# Store
|
||||
db.put(b"key", b"value")
|
||||
|
||||
# Get
|
||||
db.get(b"key")
|
||||
|
||||
# Delete
|
||||
db.delete(b"key")
|
||||
|
||||
It is also possible to gather modifications and
|
||||
apply them in a single operation ::
|
||||
|
||||
batch = rocksdb.WriteBatch()
|
||||
batch.put(b"key", b"v1")
|
||||
batch.delete(b"key")
|
||||
batch.put(b"key", b"v2")
|
||||
batch.put(b"key", b"v3")
|
||||
|
||||
db.write(batch)
|
||||
|
||||
Fetch of multiple values at once ::
|
||||
|
||||
db.put(b"key1", b"v1")
|
||||
db.put(b"key2", b"v2")
|
||||
|
||||
ret = db.multi_get([b"key1", b"key2", b"key3"])
|
||||
|
||||
# prints b"v1"
|
||||
print ret[b"key1"]
|
||||
|
||||
# prints None
|
||||
print ret[b"key3"]
|
||||
|
||||
Iteration
|
||||
=========
|
||||
|
||||
Iterators behave slightly different than expected. Per default they are not
|
||||
valid. So you have to call one of its seek methods first ::
|
||||
|
||||
db.put(b"key1", b"v1")
|
||||
db.put(b"key2", b"v2")
|
||||
db.put(b"key3", b"v3")
|
||||
|
||||
it = db.iterkeys()
|
||||
it.seek_to_first()
|
||||
|
||||
# prints [b'key1', b'key2', b'key3']
|
||||
print list(it)
|
||||
|
||||
it.seek_to_last()
|
||||
# prints [b'key3']
|
||||
print list(it)
|
||||
|
||||
it.seek(b'key2')
|
||||
# prints [b'key2', b'key3']
|
||||
print list(it)
|
||||
|
||||
There are also methods to iterate over values/items ::
|
||||
|
||||
it = db.itervalues()
|
||||
it.seek_to_first()
|
||||
|
||||
# prints [b'v1', b'v2', b'v3']
|
||||
print list(it)
|
||||
|
||||
it = db.iteritems()
|
||||
it.seek_to_first()
|
||||
|
||||
# prints [(b'key1', b'v1'), (b'key2, b'v2'), (b'key3', b'v3')]
|
||||
print list(it)
|
||||
|
||||
Reversed iteration ::
|
||||
|
||||
it = db.iteritems()
|
||||
it.seek_to_last()
|
||||
|
||||
# prints [(b'key3', b'v3'), (b'key2', b'v2'), (b'key1', b'v1')]
|
||||
print list(reversed(it))
|
||||
|
||||
SeekForPrev (Take the example from `https://github.com/facebook/rocksdb/wiki/SeekForPrev`)::
|
||||
|
||||
db.put(b'a1', b'a1_value')
|
||||
db.put(b'a3', b'a3_value')
|
||||
db.put(b'b1', b'b1_value')
|
||||
db.put(b'b2', b'b2_value')
|
||||
db.put(b'c2', b'c2_value')
|
||||
db.put(b'c4', b'c4_value')
|
||||
|
||||
it = db.iteritems()
|
||||
it.seek(b'a1')
|
||||
assertEqual(it.get(), (b'a1', b'a1_value'))
|
||||
it.seek(b'a3')
|
||||
assertEqual(it.get(), (b'a3', b'a3_value'))
|
||||
it.seek_for_prev(b'c4')
|
||||
assertEqual(it.get(), (b'c4', b'c4_value'))
|
||||
it.seek_for_prev(b'c3')
|
||||
assertEqual(it.get(), (b'c2', b'c2_value'))
|
||||
|
||||
|
||||
Snapshots
|
||||
=========
|
||||
|
||||
Snapshots are nice to get a consistent view on the database ::
|
||||
|
||||
self.db.put(b"a", b"1")
|
||||
self.db.put(b"b", b"2")
|
||||
|
||||
snapshot = self.db.snapshot()
|
||||
self.db.put(b"a", b"2")
|
||||
self.db.delete(b"b")
|
||||
|
||||
it = self.db.iteritems()
|
||||
it.seek_to_first()
|
||||
|
||||
# prints {b'a': b'2'}
|
||||
print dict(it)
|
||||
|
||||
it = self.db.iteritems(snapshot=snapshot)
|
||||
it.seek_to_first()
|
||||
|
||||
# prints {b'a': b'1', b'b': b'2'}
|
||||
print dict(it)
|
||||
|
||||
|
||||
MergeOperator
|
||||
=============
|
||||
|
||||
Merge operators are useful for efficient read-modify-write operations.
|
||||
For more details see `Merge Operator <https://github.com/facebook/rocksdb/wiki/Merge-Operator>`_
|
||||
|
||||
A python merge operator must either implement the
|
||||
:py:class:`rocksdb.interfaces.AssociativeMergeOperator` or
|
||||
:py:class:`rocksdb.interfaces.MergeOperator` interface.
|
||||
|
||||
The following example python merge operator implements a counter ::
|
||||
|
||||
class AssocCounter(rocksdb.interfaces.AssociativeMergeOperator):
|
||||
def merge(self, key, existing_value, value):
|
||||
if existing_value:
|
||||
s = int(existing_value) + int(value)
|
||||
return (True, str(s).encode('ascii'))
|
||||
return (True, value)
|
||||
|
||||
def name(self):
|
||||
return b'AssocCounter'
|
||||
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.create_if_missing = True
|
||||
opts.merge_operator = AssocCounter()
|
||||
db = rocksdb.DB('test.db', opts)
|
||||
|
||||
db.merge(b"a", b"1")
|
||||
db.merge(b"a", b"1")
|
||||
|
||||
# prints b'2'
|
||||
print db.get(b"a")
|
||||
|
||||
We provide a set of default operators ``rocksdb.merge_operators.UintAddOperator`` and ``rocksdb.merge_operators.StringAppendOperator``::
|
||||
|
||||
from rocksdb.merge_operators import UintAddOperator, StringAppendOperator
|
||||
opts = rocksdb.Options()
|
||||
opts.create_if_missing = True
|
||||
# you should also play with StringAppendOperator
|
||||
opts.merge_operator = UintAddOperator()
|
||||
db = rocksdb.DB('/tmp/test', opts)
|
||||
self.db.put(b'a', struct.pack('Q', 5566))
|
||||
for x in range(1000):
|
||||
self.db.merge(b"a", struct.pack('Q', x))
|
||||
self.assertEqual(5566 + sum(range(1000)), struct.unpack('Q', self.db.get(b'a'))[0])
|
||||
|
||||
|
||||
|
||||
PrefixExtractor
|
||||
===============
|
||||
|
||||
According to `Prefix API <https://github.com/facebook/rocksdb/wiki/Proposal-for-prefix-API>`_
|
||||
a prefix_extractor can reduce IO for scans within a prefix range.
|
||||
A python prefix extractor must implement the :py:class:`rocksdb.interfaces.SliceTransform` interface.
|
||||
|
||||
The following example presents a prefix extractor of a static size.
|
||||
So always the first 5 bytes are used as the prefix ::
|
||||
|
||||
class StaticPrefix(rocksdb.interfaces.SliceTransform):
|
||||
def name(self):
|
||||
return b'static'
|
||||
|
||||
def transform(self, src):
|
||||
return (0, 5)
|
||||
|
||||
def in_domain(self, src):
|
||||
return len(src) >= 5
|
||||
|
||||
def in_range(self, dst):
|
||||
return len(dst) == 5
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.create_if_missing=True
|
||||
opts.prefix_extractor = StaticPrefix()
|
||||
|
||||
db = rocksdb.DB('test.db', opts)
|
||||
|
||||
db.put(b'00001.x', b'x')
|
||||
db.put(b'00001.y', b'y')
|
||||
db.put(b'00001.z', b'z')
|
||||
|
||||
db.put(b'00002.x', b'x')
|
||||
db.put(b'00002.y', b'y')
|
||||
db.put(b'00002.z', b'z')
|
||||
|
||||
db.put(b'00003.x', b'x')
|
||||
db.put(b'00003.y', b'y')
|
||||
db.put(b'00003.z', b'z')
|
||||
|
||||
prefix = b'00002'
|
||||
|
||||
it = db.iteritems()
|
||||
it.seek(prefix)
|
||||
|
||||
# prints {b'00002.z': b'z', b'00002.y': b'y', b'00002.x': b'x'}
|
||||
print dict(itertools.takewhile(lambda item: item[0].startswith(prefix), it))
|
||||
|
||||
|
||||
Backup And Restore
|
||||
==================
|
||||
|
||||
Backup and Restore is done with a separate :py:class:`rocksdb.BackupEngine` object.
|
||||
|
||||
A backup can only be created on a living database object. ::
|
||||
|
||||
import rocksdb
|
||||
|
||||
db = rocksdb.DB("test.db", rocksdb.Options(create_if_missing=True))
|
||||
db.put(b'a', b'v1')
|
||||
db.put(b'b', b'v2')
|
||||
db.put(b'c', b'v3')
|
||||
|
||||
Backup is created like this.
|
||||
You can choose any path for the backup destination except the db path itself.
|
||||
If ``flush_before_backup`` is ``True`` the current memtable is flushed to disk
|
||||
before backup. ::
|
||||
|
||||
backup = rocksdb.BackupEngine("test.db/backups")
|
||||
backup.create_backup(db, flush_before_backup=True)
|
||||
|
||||
Restore is done like this.
|
||||
The two arguments are the db_dir and wal_dir, which are mostly the same. ::
|
||||
|
||||
backup = rocksdb.BackupEngine("test.db/backups")
|
||||
backup.restore_latest_backup("test.db", "test.db")
|
||||
|
||||
|
||||
Change Memtable Or SST Implementations
|
||||
======================================
|
||||
|
||||
As noted here :ref:`memtable_factories_label`, RocksDB offers different implementations for the memtable
|
||||
representation. Per default :py:class:`rocksdb.SkipListMemtableFactory` is used,
|
||||
but changing it to a different one is veary easy.
|
||||
|
||||
Here is an example for HashSkipList-MemtableFactory.
|
||||
Keep in mind: To use the hashed based MemtableFactories you must set
|
||||
:py:attr:`rocksdb.Options.prefix_extractor`.
|
||||
In this example all keys have a static prefix of len 5. ::
|
||||
|
||||
class StaticPrefix(rocksdb.interfaces.SliceTransform):
|
||||
def name(self):
|
||||
return b'static'
|
||||
|
||||
def transform(self, src):
|
||||
return (0, 5)
|
||||
|
||||
def in_domain(self, src):
|
||||
return len(src) >= 5
|
||||
|
||||
def in_range(self, dst):
|
||||
return len(dst) == 5
|
||||
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.prefix_extractor = StaticPrefix()
|
||||
opts.allow_concurrent_memtable_write = False
|
||||
opts.memtable_factory = rocksdb.HashSkipListMemtableFactory()
|
||||
opts.create_if_missing = True
|
||||
|
||||
db = rocksdb.DB("test.db", opts)
|
||||
db.put(b'00001.x', b'x')
|
||||
db.put(b'00001.y', b'y')
|
||||
db.put(b'00002.x', b'x')
|
||||
|
||||
For initial bulk loads the Vector-MemtableFactory makes sense. ::
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.allow_concurrent_memtable_write = False
|
||||
opts.memtable_factory = rocksdb.VectorMemtableFactory()
|
||||
opts.create_if_missing = True
|
||||
|
||||
db = rocksdb.DB("test.db", opts)
|
||||
|
||||
As noted here :ref:`table_factories_label`, it is also possible to change the
|
||||
representation of the final data files.
|
||||
Here is an example how to use a 'PlainTable'. ::
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.table_factory = rocksdb.PlainTableFactory()
|
||||
opts.create_if_missing = True
|
||||
|
||||
db = rocksdb.DB("test.db", opts)
|
||||
|
||||
Change Compaction Style
|
||||
=======================
|
||||
|
||||
RocksDB has a compaction algorithm called *universal*. This style typically
|
||||
results in lower write amplification but higher space amplification than
|
||||
Level Style Compaction. See here for more details,
|
||||
https://github.com/facebook/rocksdb/wiki/Rocksdb-Architecture-Guide#multi-threaded-compactions
|
||||
|
||||
Here is an example to switch to *universal style compaction*. ::
|
||||
|
||||
opts = rocksdb.Options()
|
||||
opts.compaction_style = "universal"
|
||||
opts.compaction_options_universal = {"min_merge_width": 3}
|
||||
|
||||
See here for more options on *universal style compaction*,
|
||||
:py:attr:`rocksdb.Options.compaction_options_universal`
|
||||
|
||||
Iterate Over WriteBatch
|
||||
=======================
|
||||
|
||||
In same cases you need to know, what operations happened on a WriteBatch.
|
||||
The pyrocksdb WriteBatch supports the iterator protocol, see this example. ::
|
||||
|
||||
batch = rocksdb.WriteBatch()
|
||||
batch.put(b"key1", b"v1")
|
||||
batch.delete(b'a')
|
||||
batch.merge(b'xxx', b'value')
|
||||
|
||||
for op, key, value in batch:
|
||||
print op, key, value
|
||||
|
||||
# prints the following three lines
|
||||
# Put key1 v1
|
||||
# Delete a
|
||||
# Merge xxx value
