In Amazon SQS queue do we have a limit on number distinct group ids?

I am using SQS queue to solve a business need wherein, Messages belonging to the same product needs to be executed strictly in a sequence but messages of different products can be executed in parallel.

I was hoping, if using my product_id as my group id will solve the problem but do we have any limitation on number of distinct group ids that SQS queue can hold?

Thanks in advance

  • Does not look like it, https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html says:

    There is no quota to the number of message groups within a FIFO queue.

    You only have to watch out not to have too many messages in-flight being processed by your consumers but not yet deleted, as https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/using-messagegroupid-property.html says:

    there can be a maximum of 20,000 inflight messages
