Managing Long Running Tasks hard
Why is it harder to scale a FIFO (First-In-First-Out) queue compared to a standard queue?
- A Strict ordering prevents parallel processing of that specific message group. You effectively serialize consumption to 1 worker (or shard), capping throughput.
- B FIFO queues are expensive.
- C FIFO queues don't support encryption.
- D FIFO queues are slow.
Answer: A. Strict ordering prevents parallel processing of that specific message group. You effectively serialize consumption to 1 worker (or shard), capping throughput.
Standard queues allow 1000 workers to grab any message. FIFO forces Worker 2 to wait for Worker 1.
One system design question a day, with spaced repetition so the ones you miss come back.
