Subject Re: [DISCUSS] Artemis missing advisories and producer tracking
Date Wed, 12 Oct 2016 14:17:58 GMT
+1 for supporting all the advisories that the current ActiveMQ 5.x supports.

As for when the advisory message is sent for a Producer, I'm not sure there
is a specific guarantee about that. If a Producer is 'created', but a
message is never sent, was it actually created? I'm not necessarily opposed
to the lazy notification strategy.
