> Key: ARTEMIS-1162
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1162
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Affects Versions: 2.1.0
> Reporter: Michael Andre Pearce
> Fix For: 2.2.0
>
>
> New Adapting TimedBuffer was added and replaced existing Fixed TimedBuffer.
> This could cause behaviour/performance change of journal IO (and hopefully
> for the better).
> As this hasn't been run significantly in a real world production environment,
> to avoid causing any production deployment issues having unexpected behaviour
> changes, or to allow managed rollout and rollback.
> We would like to add back the fixed timed buffer (default), and make it
> configurable to the new improved timed buffer.
