---------------------------------------------
Assignee: Michael Andre Pearce
> Enhanced Message Groups Support
> --------------------------------
>
> Key: ARTEMIS-2118
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2118
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Reporter: Michael Andre Pearce
> Assignee: Michael Andre Pearce
> Priority: Major
>
> 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.
