> This ticket is for supporting some Message Group Enhancements.
>  
> Currently Artemis implements message groups in a simple way, equivalent to SimpleMessageGroupMap in activemq5.
> [http://activemq.apache.org/message-groups.html]
> "SimpleMessageGroupMap keeps track of every group but suffers from unbounded memory use."
>  
> For use cases migrating from activemq5 its important artemis supports similar
> MessageGroupHashBucked feature.
> "MessageGroupHashBucked keeps track of every group and has bounded memory use."
> As such, this JIRA is to add support for being able to enable a semantic equivalent to MessageGroupHashBucket from activemq5, at the queue level.
>  
> Also currently it is not possible for a specific queue disable grouping, this can be useful where a shared address by many queues, where some consumers care for ordering and others do not.
> Lastly add an ability to rebalance message groups when a consumer is added, this is useful where you want groups more evenly balanced when consumers come online, even after dispatching started.
