Where have the Repo.Pools gone

Hi everyone,

In Programming Phoenix > 1.4 – Introspecting Applications with Observer subchapter, there is an image that displays, amongst others, Elixir.Rumbl.Repo.Pool in the Applications tab of the observer. (sorry, as a new user i can’t upload images)

I understand that immediately after, it says You May Have a Different Supervision Tree but I was just wondering where the pool has gone? Does it still exist?

Apologies if the question wasn’t clear ! Here’s the Applications graph from the book

And here’s the Applications graph with latest deps

Is the connection pool abstracted? Was it refactored? Or are the connections in the pool spun up on-demand now?

I think it is now in db_connection application. Check its supervision tree.
