Assignee: Matt Pavlovich
> Allow AbortSlowConsumerStrategy to specify a fixed number of pending messages
> to consider a consumer slow
> ---------------------------------------------------------------------------------------------------------
>
> Key: AMQ-5625
> URL: https://issues.apache.org/jira/browse/AMQ-5625
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 5.8.0
> Reporter: Tim Bain
> Assignee: Matt Pavlovich
> Priority: Major
> Fix For: 5.18.3, 5.19.1
>
>
> Currently, the AbortSlowConsumerStrategy considers a consumer to be slow when
> the broker has a number of pending messages equal to the consumer's prefetch
> buffer size.
> It would be useful to be able to specify directly the number of messages that
> must be pending to consider the consumer slow, irrespective of the consumer's
> prefetch size.
> This would be especially useful for consumers with a very small prefetch size
> (e.g. 1), to allow them to meaningfully use the AbortSlowConsumerStrategy
> instead of being forced to use the AbortSlowAckConsumerStrategy (which
> protects against a very different kind of problem). But it would also be
> useful for consumers with larger prefetch buffers if we want to consider the
> consumer slow sooner than the point where there are an additional prefetch
> buffer worth of pending message; this is especially true for anyone using the
> default prefetch size of 32k messages for non-persistent topics.
