DBOS documents three changes that took Postgres-backed queues to 30,000 workflows per second

Sources: primary, discussion
Summary: DBOS names three changes behind a reported 30,000 workflows per second on Postgres-backed queues: SKIP LOCKED on dequeue, dropping the dequeue transaction from REPEATABLE READ to READ COMMITTED where no global concurrency limit is needed, and partial indexes scoped to the ENQUEUED state. The page's visible byline reads 2026-06-02 while its structured metadata gives a datePublished of 2026-07-30, so no publication date is asserted here.
Why it matters: The three changes are concrete things to check before replacing a Postgres queue with a dedicated broker.
