Subject Re: Difference between kahaPersistenceAdapter and kahaDB
Date Thu, 11 Nov 2010 10:47:59 GMT

Thanks Gary...
 You suggest using KahaDB over KahaPersistenceAdapter because of more
development activity and support. 
However, I have significant performance issues with KahaDB. From my tests,
KahaBD performance is heavily dependent on the maximum sync rate of the
filesystem. 
KahaPersistenceAdapter is generally faster as described. 
My questions are: 
-enableJournalDiskSyncs="false" speeds up KahaDB a lot, but, does it
guarantee persistence of messages in all cases?

-is KahaPersistenceAdapter as reliable as KahaDB? 
-does it guarantee persistence of queues? I do not need Topic durable
subscriptions, only guaranteed delivery for queues
