Subject [DISCUSS] FALCON-1889 JMS user notification creates a topic per feed/process
Date Tue, 19 Apr 2016 22:37:38 GMT
JIRA - https://issues.apache.org/jira/browse/FALCON-1889
Documentation - https://falcon.apache.org/Operability.html

Falcon creates a topic per feed/process for user notification. ActiveMQ is
the usual/default JMS provider used/integrated with Falcon and a topic
(with persistent consumer) in ActiveMQ will require a file handle and so
for larger number of feed/process combination, this approach is not
scalable eclipsed by resource constraints and leaks.

The other option is to have one topic but the map message to have feed or
process entity name. There is already a FALCON.ENTITY.TOPIC that meets the
requirement.

With that said, what is the use case and requirements around the user
notification with per feed/process JMS topic? I would propose to deprecate
it and add any other required info to the FALCON.ENTITY.TOPIC or create a
new one topic that satisfies all the needs.

Thanks
Venky
