Final answer:
The throughput limit for an Amazon SQS FIFO queue is 300 TPS with batching, but it can be increased with a support request. The throughput limit for an Amazon SQS FIFO queue is 300 transactions per second, with the option to increase throughput using message batching or multiple queues.
Step-by-step explanation:
The throughput limit for an Amazon SQS FIFO (First-In-First-Out) queue depends on the message size and is measured in transactions per second (TPS). The standard throughput limit is 300 TPS with batching, which means that you can send up to 300 messages per second with batching enabled. If you require a higher throughput, you can request a limit increase by contacting AWS Support.
It's important to note that the throughput limit can be impacted by factors such as the message size, message grouping, and the number of both inflight and queued messages. You should also consider that different Amazon SQS features have different limits, so you may need to adjust your design accordingly.
