Artemis: how to prevent auto-deletion of topics?

Greetings!

Using JMS drivers, we are finding that auto-created topics are deleted after all consumers go away, but then the topic is not automatically re-created when still-active producers post.  This seems to fail silently and is basically the same behavior I reported earlier with regard to auto-deleted queues.

I’ve been able to suppress auto-deletion of queues (see broker.xml below) but topics continue to be auto-deleted.  Do I need to create topics differently?  Is there a broker setting I am missing?

Thanks
John

RE: Artemis: how to prevent auto-deletion of topics?

Posted by John Lilley <jo...@redpointglobal.com.INVALID>.
UPDATE: It doesn’t matter with topics.  Topics seem to be well-behaved, in the sense that topics that are auto-deleted while there are active producers are re-created as soon as a message is published.  This is not true with queues, where auto-deletion effectively breaks all current producers.  We’ve worked around queue auto-delete and I’ll file a bug report for it.

Thanks
John
