20.9.5. Best Practices for Clustered Grouping

Some best practices for clustered grouping are as follows:
  • If you create and close consumers regularly make sure that your consumers are distributed evenly across the different nodes. Once a queue is pinned, messages are automatically transferred to that queue regardless of removing customers from it
  • If you wish to remove a queue which has a message group bound to it, make sure the queue is deleted by the session that is sending the messages. Doing this will ensure that other nodes will not try to route messages to this queue after it is removed
  • As a failover mechanism always replicate the node which has the local grouping handler
