Key: JBMESSAGING-604
URL:
http://jira.jboss.com/jira/browse/JBMESSAGING-604
Project: JBoss Messaging
Issue Type: Feature Request
Reporter: Tim Fox
Assigned To: Tim Fox
Fix For: 1.2.1
Whereas JMS requires once and only once *delivery* of messages, there are no such
guarantees when sending messages to a queue/durable sub.
This can result in duplicate messages existing in a queue or durable sub.
For some clients this is unacceptable, so we should implement a feature which alerts to
the presence of duplicates.
This can be done by keeping a persistent cache of message (or transaction) id on the
server. Entries should time out after a period of time.
This will not remove duplicates 100% of the time since we cannot cache the previous
values of id for ever, but only for a window.
