I have a rails app that uses MySQL for authentication and storing models. I currently am thinking of using PostgreSQL for analytics (by taking advantage of its special data types like arrays and KV pairs). I am just wondering how I would be able to have two types of databases (1 for models and authentication and 1 for analytics) when trying to save records using ActiveRecord. I want to save the model for analytics in Postgres and other models in MySQL.
My advice would be to migrate completely to PostgresSQL if you want to use it for anything. It’ll make your life a lot simpler.
I believe your best answer otherwise will be to stop inheriting from ActiveRecord::Base for your models here. Instead include ActiveRecord, and manually call establish_connection.
But yeah, just migrate to PG. It’ll save a lot of trouble.
