Subject Failover and non-persistent messages
Date Tue, 28 Jan 2014 00:31:07 GMT
In our application we want to use non-persistent messages but benefit from
failover (ie master-slave configuration using kahadb).

I did some experiments today and contrary to my expectations it looks like
activemq 5.9.0 supports this scenario.  Huzzah! I had a producer and
consumer connecting to a topic and stopped the master server in
mid-execution.  The producer switched over to the slave broker, as did the

My questions for you kind folks:

1. Are my findings valid?  That is, does activemq 5.9.0 support master/slave
failover with non-persistent messages?
2. We are leaning towards kahadb as the most stable and performant solution
for failover; is this true?
3. The default 10 second lock check is going to be too slow for our
application... I'd like to make this number as small as possible.  Any
guidance?  Is a sub-second value too much to ask for?

Thanks for any help!
