A backtest worker and a live trading node had to share one broker rate limit and one set of OAuth tokens, and both only work if there’s exactly one of them in the cluster. Instead of adding Redis, I registered the token stores and the rate limiter in :global and let Oban use Postgres as the queue. The token stores kept their refresh and retry behavior instead of turning into keys two clients race to update. The rate limiter had to give up its direct ETS writes to become correct across nodes, and the post covers what I traded for that, plus an Oban queue config that merged when I thought it overrode.
