Chihaya 
Chihaya is a high-performance BitTorrent tracker written in the Go programming language. It is still heavily under development and should not be used in production. Some of the planned features include.
- Low resource consumption
- Fast request processing
- Maximum compatibility with what exists of the BitTorrent spec
- Correct IPv6 support
- A generic storage interfaces that is easily adapted to use any data store and web application
- Scaling properties that directly correlate with those of the chosen data stores
Architecture
You are most likely looking to integrate Chihaya with a web application for organizing torrents and managing a community. Chihaya was designed with this in mind, but also tries to remain independent. Chihaya connects to two data stores. The first, known as "cache", is used between Chihaya processes in order to keep up with fast changing data. The second, known as "storage", is your web application's data store. Changes immediately take place in the cache, which is why fast data stores are recommended. These changes are also collected and periodically applied to the storage in order to avoid locking up your web application's data store.
Installing
Make sure you have your $GOROOT and $GOPATH set up correctly and have your $GOBIN on your $PATH.
$ go install github.com/pushrax/chihaya
Configuring
Configuration is done in a JSON formatted file specified with the -config
flag. An example configuration can be seen in the exampleConfig variable of
config/config_test.go.
Default drivers
Cache
Chihaya currently supports drivers for the following caches out of the box:
Storage
Chihaya currently supports drivers for the following storages out of the box:
Custom drivers
Please read the documentation and understand these interfaces as there are
assumptions made about thread-safety. After you've implemented a new driver,
all you have to do is remember to add import _ path/to/your/package to the
top of main.go and the side effects from init() will globally register
your driver so that config package will recognize your driver by name.
If you're writing a driver for a popular data store, consider contributing it.
Cache
The cache package is heavily inspired by the standard library's
database/sql package. To write a new cache backend, create a new Go
package that has an implementation of the Pool, Tx, and Driver
interfaces. Within that package, you must also define an init() that calls
cache.Register.

Contributing
If you're interested in contributing, please contact us in #chihaya on [freenode IRC] or post to the GitHub issue tracker. Please don't offer massive pull requests with no prior communication attempts as it will most likely lead to confusion and time wasted for everyone. However, small unannounced fixes are always welcome.
And remember: good gophers always use gofmt!
