Do I need to create multiple instances of Sequelize if I want to use two databases? That is, two databases on the same machine.
If not, what\'s the proper way to do
if you are trying to associate objects in the same RDS across multiple databases, you can use schema.
http://docs.sequelizejs.com/class/lib/model.js~Model.html#static-method-schema
this will prepend the db name to the table name so, presumably, your queries would come out like:
SELECT A.ColA, B.ColB FROM SchemaA.ATable A INNER JOIN SchemaB.BTable B ON B.BId = A.BId
