Partitioned Queue and Topic Subscription

A few thoughts:

  1. If you only have one db in your “db + topic” scenario does it need to be an XA transaction. Will a regular transaction not suffice?
  2. Some Transaction Managers (not all) support the concept of “last participant”. If yours does, could this be an option?
  3. Before we had Partitioned Queues we used to use a pattern for Sticky Load Balancing between queues when message order is important that is explained in this blog: https://solace.com/blog/sticky-load-balancing-in-solace-pubsub-event-broker/

Hope this helps.
