[jboss-jira] [JBoss JIRA] (JBMESSAGING-1621) Provide complete message ordering in a clustered environment

Provide complete message ordering in a clustered environment ------------------------------------------------------------ Key: JBMESSAGING-1621 URL: https://issues.jboss.org/browse/JBMESSAGING-1621 Project: JBoss Messaging Issue Type: Feature Request Components: JMS Clustering Affects Versions: 1.4.0.SP3.CP08, 1.4.4.GA Reporter: Yusuke Yamamoto Assignee: Yong Hao Gao Fix For: 1.4.0.SP3.CP15, 1.4.8.SP6 While JBMESSAGING-1416 states message ordering feature in a singleton configuration, customer is also requesting a complete message ordering feature which is applicable in a clustered environment. Here's the background: In the case JMS is used, both performance and scalability are priority. There is a conflict between scalable JMS implementation and complete message ordering feature since order aware messages cannot be processed concurrently. But order unaware queues should be still processed in parallel for better throughput. Additionally, there are some cases that no downtime is acceptable. But HA-Singleton requires certain amount of time to fail-over the service to other node.
