---------------------------------------------
Summary: Support Hash Bucket MessageGroup equivalent from ActiveMQ5
Key: ARTEMIS-2118
URL: https://issues.apache.org/jira/browse/ARTEMIS-2118
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Reporter: Michael Andre Pearce
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 JITA is to add support for being able to enable a semantic
equivalent to MessageGroupHashBucket from activemq5, at the queue level.
