Hi there. We use the mysql\_replication\_adapter gem for our Rails app (1 master, 4 slaves). It was incompatible with Rails 2.2, so I updated it and put it on github to share. If you have a database cluster and aren’t using mysql\_replication\_adapter, what are you using? Read about the update here: [http://www.foundchris.com/2009/02/12/rails-plugin-mysql\_replication\_adapter-for-rails-22/](http://www.foundchris.com/2009/02/12/rails-plugin-mysql_replication_adapter-for-rails-22/) Hope this helps someone. -Chris ---

Hi Chris, I rolled my own solution after Masochism stopped working, much like what you did, but with only one slave config, sharing between slaves would be done by using a round-robin dns update. Also, does it really needs to be done MySQL specific? Your database adapter could just use the “mysql\_connection” method to create a connection instead of using database specific code. - Maurício Linhares [http://alinhavado.wordpress.com/](http://alinhavado.wordpress.com/) (pt-br) | [http://blog.codevader.com/](http://blog.codevader.com/) (en) ---

Hi Mauricio. Thanks for your reply. I only needed a mysql adapter. Feel free to fork the repos to work on abstracting it, and I’ll gladly accept pull requests. -Chris On Feb 19, 6:02 pm, Maurício Linhares [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
