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
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
