[jboss-jira] [JBoss JIRA] (AS7-1534) Ability to use alternate persistent stores for EJB timers

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12739077#comment-12739077 ] 

Stuart Douglas commented on AS7-1534:
-------------------------------------

I have decided against using infinispan for now, and have a simple JDBC based version that is nearly complete. This JDBC store should eventually also support the clustered timers use case, using database level locks / optimistic locking to prevent timers being run on multiple nodes. 

This approach is probably not as efficient as using a 'proper' cluster data store, however it is much simpler, as we simply do not have the resources to implement high performance clustered timers at the moment. This should only be an issue in environments where it is expected that multiple timers are going off every second. 

This database backed approach does not preclude adding infinispan backed timers at some point in the future (in fact, after this patch it would be possible to add them via a 3rd party subsystem).
