How can I implement a database-level multi-tenancy feature in Rails6 that allows me to dynamically add databases in runtime?

Question

I want to implement a database-level multi-tenancy feature that allows me to add databases dynamically. I haven't found a way to do this in Rails6. Can Rails6's multi-database feature dynamically recognize a new database if it's added while the application is running?

If anyone knows, please advise.

Answer 1

Have you looked into apartment gem ? It has API to create new DBs during runtime and switch to them. I have used it successfully on rails 5.2 but haven't tried on rails 6 (YMMV). You can also leverage Rails 6's multi-database feature to create and switch to DBs in runtime (requires little bit of in depth Rails connection pool knowledge), but when I tried with rails 6.0, I was forced to establish new connection on every request, which made things slow and unusable. Hope this helps and good luck!
