title: In Amazon SQS queue do we have a limit on number distinct group ids?
body: <p>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.</p>
  <p>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?</p>
  <p>Thanks in advance</p>
