Subject Re: Encourage more users to embed activemq?
Date Fri, 17 Apr 2015 18:53:55 GMT
If you embed it in your app, then you lose the ability to cycle your app
without taking down your broker (which is a bad thing if you use
non-persistent messaging as we do).  Clearly that trade-off is a win in
your situation, but your situation's a bit of an outlier in terms of
performance, so the forces that drive you to embed may not be applicable to
users with more mainstream performance requirements.

With that being said, I'd be really interested in the ability to expose a
RESTful API around the broker so you can get JMX stats faster than JMX will
allow, because we've been hampered by how slow JMX is.  We're trying to
poll dozens/hundreds of destination/consumer/producer MBeans every
second to log out status (to help us look for sources of lag within the
system), and JMX is completely unable to keep up, so we'd love a better
option.  I'm not sure if that would be done by embedding ActiveMQ within an
app that provides only that RESTful API or by rolling the API into the core
broker executable, but if you're still thinking of open-sourcing that code
(whether as part of the ActiveMQ project or as a companion project), we'd
be interested in using it.
