Add and test functions which can be used to write optional transaction labels to disk in their own bucket. These labels are keyed by txid and write the labels to disk using-length value encoding scheme. Although the length field is not required at present, it is added to allow future extensibility without a migration. This approach is chosen over adding this information to txRecords, Because a migration would be required to add a field after the variable Length serialized tx. The put label function will overwrite existing labels if called more than once for the same txid. User side validation of whether we want to override this label should be performed by calling code. Labels must be > 0 characters and <= 500 characters (an arbitrarily chosen limit). |
