> Project: ActiveMQ
> Issue Type: Improvement
> Components: Message Store
> Affects Versions: 5.11.0

> Labels: journal, kahaDB, perfomance
> Fix For: 5.12.0

>
> Our journals are append only, however we use the size to track journal
> rollover on recovery and replay. We can improve performance if we never
> update the size on disk and preallocate on creation.
> Rework journal logic to ensure size is never updated. This will allow the
> configuration option from https://issues.apache.org/jira/browse/AMQ-4947 to
> be the default.
