Subject [jira] [Commented] (HCATALOG-3) Send a message on a message bus when events occur in Metastore
Date Wed, 18 May 2011 20:06:47 GMT

    [ https://issues.apache.org/jira/browse/HCATALOG-3?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13035628#comment-13035628

Jakob Homan commented on HCATALOG-3:
------------------------------------

I'm not requesting to drop JMS, just to keep it cleanly integrated so (1) it would be easy
to test via mocking or such to avoid the activemq inclusion and (2) so that later on, we could
contribute a patch to make other systems, like Kafka, work.  Messaging is general enough that
it should be relatively straightforward to have a clean interface around it.  Since I don't
have a patch ready for something like supporting Kafka, I'm certainly not trying to block
JMS.
