masochism
==============
The masochism plugin provides an easy solution for Ruby on Rails applications to
work in a replicated database environment. Connection proxy sends some database
queries (those in a transaction, update statements, and ActiveRecord::Base#reload)
to a master database, and the rest to the slave database.
The ActiveReload::MasterDatabase model uses a 'master_database' setting in
database.yml to serve as the master database.
# config/database.yml
login: &login
adapter: postgresql
host: localhost
port: 5432
production:
database: slave_database_name
<<: *login
master_database:
database: master_database_name
<<: *login
To setup:
Whether you want this in production only, or maybe just your deployment server,
is up to you. Just call the following method in your desired environment file.
ActiveReload::ConnectionProxy.setup!
Some suggestions:
* in a config/initializer
* config.after_initialize block
If you want a model to always use the Master database, you can inherit
ActiveRelaod::MasterDatabase. Any models with their own database connection
will not be affected.
Setting up your own proxies:
# Sets up MyMaster's connection as the master database connection for User.
ActiveReload::ConnectionProxy.setup_for MyMaster, User
