Yes, I think there are many things I could write about "pains and gotchas" :)

Regarding RDS, is an interesting thing. We are migrating from a Rails app where all the servers were connecting to the same database, as also multiple Sidekiq workers. It required a lot of open connections to handle that.

We now have a quite simple setup where a small pool of connections can easily handle that, even with traffic always hitting the database :)

Yeah I guess that's a nice side effect, with Elixir you might get more control over your whole system (including "external" resources like databases) because it's so easy to reason about what is running concurrently.

Pretty cool!
