Subject Re: Nothing on queues, Journal files not getting cleaned up
Date Tue, 29 Sep 2015 15:34:07 GMT
There is no option to compact KahaDB.  The current solution for the problem
of journal files not being cleaned up is to use multi kahadb.  Gary has a
good post about it here
http://blog.garytully.com/2011/11/activemq-multiple-kahadb-instances.html

There's a couple open tickets to add compaction to KahaDB.
