Subject: [hornetq-users] Does hornetq let you acknowledge from a different
	thread?
Message-ID: <A584993B-9DEC-4A17-96CA-2AA9BEAD9725@gmail.com>

If you have a pattern where you have async consumption thru message  
listener but you perform that actual processing in a worker thread is  
it possible to acknowledge the message in the worker thread with  
hornetq?

This is something JMS generally doesn't allow you to do and so you  
have a possibility of work still be queued for work in a thread pool  
and having already acknowledged the message from the queue. In the  
event of an interruption it's possible to have lost messages. In order  
to ensure that I can process my message in a thread pool and I have  
maintain state in a database which is an additional cost that I have  
per message and one I'm not comfortable with.

I would much prefer a solution that allows me to perform my work in a  
different thread but acknowledge the message only when I know I've  
processed.
