英文:
Why 4 SQS FIFO with not batch to reach 1000 msg/sec during a peak demmand and not 2 SQS FIFO each with a btach of 2 msgs?
问题
Hi guys，我想澄清一个疑问。这个问题的解决方案有点具有争议性。
Ok，你可以在批处理模式下使用4个SQS FIFO，达到每秒1200条消息的速率。
但是我可以使用2个SQS FIFO，每个批处理中有2条消息，也可以达到相同的每秒1200条消息的速率。我只是按照解决方案的理由来做，如果每个批次中有10条消息，那么每秒可以处理3000条消息，那么有2条消息的批次就是每秒600条消息。为什么不呢？
难道我漏掉了什么吗？

Hi guys I would like to take out a doubt. The solution to this question is a little bit controversial.
Ok, You can use 4 SQS FIFO in batch mode and reach the rate of 1200 msg/sec.
But I could use 2 SQS FIFO in batch mode each with a batch of 2 messages reaching the same 1200 msg/sec. I just follow the solution reason, If each with a batch of 10 has a batch of 3000 msg/sec, then with a batch of 2 messages then 600msg/sec.
Why not?
Did not I get something?

根据Amazon Simple Queue Service中的高吞吐量队列和与消息相关的配额，FIFO队列的限制是每秒300个(ReceiveMessage)操作。
如果您有1000条消息/秒：
- 1000 / 300 = 3.33，四舍五入 => 需要每批处理4条消息，以处理1000条消息/秒。
- 您的每批2条消息将仅导致读取600条消息/秒。
这些限制是每个队列的，不是每个队列的消费者的，也不是所有队列的总和。
英文:
According to High throughput for FIFO queues - Amazon Simple Queue Service and Quotas related to messages
the limit of FIFO is 300 (ReceiveMessage) operations / second.
If you have 1000 messages / s:
- 1000 / 300 = 3.33, round it up => 4 messages per batch required to process 1000 messages / s.
- Your 2 messages per batch would only result in 600 messages / s being read.
These limits are per queue, not per consumer of a queue and not across all queues.
