 Octopus  Replication Example 


 This is a sample rails application demonstrating replication features in octopus. The application have 1 master, (specified in database.yml) and 4 slaves (specified in shards.yml).


Feature list: 


 All writes will be sent to master, and the read queries will be sent to the slaves. unless you have a transaction, so , all queries will be sent to master.

 The application have two different models: Client and User. User is a replicated model, and Client isn't replicated. So, when you create a new User, you will see a exception, because you don't have configuration for replication and Rails tries to read the user from a slave database, and the write query have been sent to master (Default behaviour when using replication). When you create a new client, everything should works fine, it will read and write in the master database. 


 Setup: 

 You will need two commands to setup the application:

 rake db:octopus && rake db:migrate
