How Octopus Works

Ideas

Octopus works using the Proxy Pattern . Basically, Octopus build a proxy between ActiveRecord and Database Connection. The proxy object handles the way of executing queries, when send to multiple shards, or send to master when is replicated. Default behaviours are:

• Replication: Writes queries are sent to master, and reads queries are sent to slaves.
• Sharding: Writes/Reads queries are sent to master, unless you specified a shard to send the query.
