Subject [jira] Commented: (QPID-1677) Provide the ability to publish synchronously
Date Wed, 15 Apr 2009 13:17:15 GMT

    [ https://issues.apache.org/jira/browse/QPID-1677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699184#action_12699184

Martin Ritchie commented on QPID-1677:

Rajith, why is the setPublishMode() code in the abstract BasicMessageProducer when it is used
for 0-10 producing?

Think this code needs to be moved in to the protocol specific class.

> In order for the producer to not replay the messages again (during failover) and prevent
duplicates,we need a way for the JMS client to sync on every publish. 
> To faciliate this, I have propose a System/Connection URLproperty called sync_publish={persistent|all}
which supercedes sync_persistent.
> (sync_persistent is deprecated but supported for a few releases with a warning printed
if used).
> In order to provide exactly-once semantics between a single JMS publisher-consumer pair
(when using AUTO_ACK on the consumer) we need to publish synchronously and ack synchronously
