Subject Re: ActiveMQ and memory cache

That would be great to spike into a proof of concept. The memory
persistence adapter would be an ideal start point as it maintains some
simple in memory lists that would be easy to replicate.
Reusing something as solid as memcached makes sense if it is not too
difficult to setup and maintain.
For sure there are some usecases that would benefit from a simple
shared memory persistence impl. However dealing with message order and
concurrent consumers on the same destination will require some
thought.
