Christopher L. Shannon commented on AMQ-7015: --------------------------------------------- No problem, I was just pointing out he wasn't -1 so we can just leave it as for the 5.15.5 release because you guys feel strongly about it. And I don't want to get into a big long thing about this so this is the last thing I will say....yes they are users and sure their opinion counts of course. But since I've been part of the community for the past 3-4 years it has been pointed out numerous times that the community is everyone and more than one vendor. So I agree their opinion counts but strongly disagree that based on that you can make a blanket statement and say there is "community support" without anyone else's opinion. (Although you could probably make the argument that there is lazy consensus since no one said they disagree) > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
