module Sequel::Plugins::Sharding

  1. lib/sequel/plugins/sharding.rb

The sharding plugin augments Sequel's default model sharding support in the following ways:

  • It automatically saves model instances back to the shard they were retreived from.

  • It makes model associations use the same shard as the model object.

  • It adds a slightly nicer API for creating model instances on specific shards.

Usage:

# Add the sharding support to all model subclasses (called before loading subclasses)
Sequel::Model.plugin :sharding

# Add the sharding support to the Album class
Album.plugin :sharding
