---------------------------------------------
[~gtully], I went ahead and fixed this to just do the enum comparison so there
is no more use of String in that getter.
> Introduce a periodic disk sync mode for KahaDB journal

> Key: AMQ-6377
> URL: https://issues.apache.org/jira/browse/AMQ-6377
> Project: ActiveMQ
> Issue Type: New Feature
> Components: Broker, KahaDB
> Affects Versions: 5.13.4
> Reporter: Christopher L. Shannon
> Assignee: Christopher L. Shannon
> Fix For: 5.14.0
>
>
> KahaDB has two modes for journal disk syncs, either always sync for each
> write or never sync. I'm proposing that we add a third option, a period disk
> sync.
> The intended behavior of this would be to run a task in the file appender
> that would sync the file (if necessary) at some periodic interval (such as
> every 500 ms, or 1 second, etc) instead of every write. The file would also
> be synced on close (on file rollover or shutdown)
> In my testing, syncing every 1 second has been proven to be nearly
> indistinguishable performance as never disk syncing but is a safer option as
> you insure that a sync is performed at least once per interval.
