[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1072) Implement slow consumers flag

[Tim Fox (JIRA)]

Tim Fox commented on JBMESSAGING-1072:
--------------------------------------

Solution to this would be to add a flag on the connection factory "SlowConsumer".

This would filter through to the ServerConsumerEndpoint on creation.

If true, then the ServerConsumerEndpoint would only ever accept one message at a time and would not buffer.

> If there are slow and fast consumer(s)  consuming from the same queue, then load balancing might not work as one would expect.
> By default, each consumer has a prefetch size which determines how many messages it would accept before accepting any more.
> So if you send 100 messages, then 50 might go to the slow consumer then the other 50 the fast consumer.
> The slow consumer woud then take a long time to process the 50 messages, resulting in non optimal processing time.
