Subject Re: Ordering of persistent/non-persistent messages in ActiveMQ 5
Date Tue, 26 Feb 2008 15:22:47 GMT
Hi Rob,

Is this the same thing as the Total Ordering feature (c.f.,
http://activemq.apache.org/total-ordering.html), or is it something
different?  While it may be expected behavior, it was a little surprising to
read that was what would happen.

Best,
Jim
