Petr Kuzel commented on ARTEMIS-2897:
-------------------------------------

Well, I have re-read the slow consumer detection documentation and that is not 
an alternative. The slow consumer detection works only for the non-durable 
cases, disconnecting and discarding messages for the slow consumers.  Which is 
indeed a niche in our enterprise.

 

For the selectors, an old story, we had other designs too, but the higher perf 
non-selectors design failed because the clients prioritize ad-hoc flexibility 
provided by selectors over the higher perf. 

 

Hope it helps
