> Based on discussion at [https://community.oracle.com/tech/developers/discussion/4300421/master-fails-unexpectedly-due-to-feeder-output-halted-log-file-reading-at-file-0x334f63-offset-0x8ce] we need a way to configure broker without a coalescing committer. The local sync policy would be set as per user virtual host settings.
> A context variable can be added into BDB HA to disable coalescing committer thread.
