Description

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.
