Date Sat, 13 May 2017 08:00:14 GMT


ASF GitHub Bot commented on ARTEMIS-1162:

Github user franz1981 commented on the issue:
    @michaelandrepearce And about loosing some tests, it is not a big deal; the deleted ones
has some issues, so it has no practical effect to have them deleted.
    On the [shouldNotFlusgUntilTimeout
shows that with the original implementation was possible to go out of IOPS too.

>                 Key: ARTEMIS-1162
>                 URL:
>             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.
