Octopus is a framework for database sharding with Ruby on Rails' ActiveRecord.

From the README:

Octopus is a better way to do Database Sharding in ActiveRecord. Sharding allows multiple databases in the same rails application. While there are several projects that implement Sharding (e.g. DbCharmer, DataFabric, MultiDb), each project has its own limitations. The main goal of octopus project is to provide a better way of doing Database Sharding.

Octopus supports:

  • Sharding (with multiple shards, and grouped shards).
  • Replication (Master/slave support, with multiple slaves).
  • Moving data between shards with migrations.

Source code for Octopus is on github.
