------------------------------------
Hi Gary,
I would love to have longer conversation to that we could discuss this more
in-depth. I am a bit confused. The setting now acts nearly identical to the
MBean, but works en-masse. It allows you to select comit/rollback/ nor nothing
(default). The unit tests appear to confirm that it works whereby the commit
adds the messages through, the rollback removes them. It seems to so the same
as the MBean. Could you help explain why this new change does not work?
> Startup performance improvement when log contains prepared transactions.

> Key: AMQ-7015
> URL: https://issues.apache.org/jira/browse/AMQ-7015
> Project: ActiveMQ
> Issue Type: New Feature
> Affects Versions: 5.15.4
> Reporter: Heath Kesler
> Assignee: Jeff Genender
> Priority: Minor
> Fix For: 5.16.0, 5.15.5
>
>
> I have a KahaDB that's performing a recovery on each startup.
> Digging deeper into it I've found that the issue is that the db.log contains
> prepared transactions.
> The MessageDatabase will discard those entries in memory, however it does not
> remove transaction info from those messages (I believe that's by design). So
> on each restart, the broker will find those entries and again discard them in
> memory.
> If I access the broker via JMX, I can go to the prepared XAs and execute a
> clear on them one by one.
> When i restart my broker, i don't have a recovery attempted again.
> Performing a remove operation for each message can be very time consuming, so
> i'd like to introduce an optional parameter to allow all prepared XAs to be
> removed on recovery.
> Please see my forth coming patch with unit test.
