How SailsJS connects to mysql with replication failover?

Question

I have developed an application using SailsJS, using sails-mysql adapter. I want to setup replication and automatic failover for MySQL. In a typical java application using JConnector, I would have specify the master and slave configuration on my connection string. What about SailsJS?

Answer 1

After a few days of digging around the net. I have found the solution to use HAProxy to load balance MySQL nodes. My sails-mysql adapter will only connect to HAProxy address. There is an awesome tutorial here to setup HAProxy with MySQL.
