Subject creating a new message once all previous messages have been executed?
Date Mon, 03 Nov 2014 21:40:35 GMT
I’m curious if there is a good pattern for creating a new messages once all
previous tasks have been properly executed.

So say I have 100 A messages which are consumed by a bunch of tasks in your

When all the A tasks have executed, you want to run 1 B task to compute
their results.

So it’s sort of like map-reduce in a way.

I think what I could do is use JMS transactions, and then read the value of
an incrementing pointer, when it hits 100, I can create the B task, and
then commit() the entire session.
