> How do you process a million jobs in parallel across many machines?
Start the processes that execute the code, get notified when they are finished. Literally a couple of lines of Erlang/Elixir. Not some large framework that does all that for you, it's in the language. It is built to run a lot of tasks in parallel and across many machines.
> How do you schedule a job to run in a week?
Like anyone else, put it in some permanent storage like redis. You can also keep it in memory, you can also use mnesia which is a distributed database that comes with Erlang.
