   There may be a workable workflow for transferring ownership of a message group, where that
workflow is cooperation between Artemis and the existing consumer assigned for that message
group.
   
   What if a message group is flagged for rebalancing when the need arises. Then, the next
message to arrive in that message group is sent to the existing consumer with a special header
that informs the consumer that the message group is being reassigned. That consumer is then
expected to "release" all messages it is working on in that message group back to Artemis,
which then sends them to the newly assigned consumer for that message group.
   
   If no further message turns up, then it's not really a load balancing issue.
   
   What do you think?
