Subject [jira] [Resolved] (AMQ-3646) Allow KahaDB to run without disk syncs, higher through put without the jms persistence guarantee
Date Fri, 23 Dec 2011 15:50:30 GMT

     [ https://issues.apache.org/jira/browse/AMQ-3646?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Tully resolved AMQ-3646.
-----------------------------

    Resolution: Fixed

fix in http://svn.apache.org/viewvc?rev=1222705&view=rev

A checkpoint won't disk sync when setEnableJournalDiskSyncs=false on kahaDB. Checkpoint and
cleanup can be disabled altogether with a period of 0. The broker jmx view {{gc()}} operation
will do a persistence adapter checkpoint/cleanup so it is possible to manually force a gc
of the store.

> When using the broker as a buffer for persistent data, large bursts or additions, periodic
batch removes, we want to become disk bound. Waiting for disk syncs causes unnecessary pauses.
If the JMS durability guarantee is not needed, it should be possible to execute without disk
syncs. Syncing only on shutdown.
