[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1427) Optimize Journal for Lazy-destinations

[ https://jira.jboss.org/jira/browse/JBMESSAGING-1427?page=com.atlassian.ji... ] Tim Fox commented on JBMESSAGING-1427: -------------------------------------- I don't believe the lazy destination approach will work, since the user will need to know in advance which destinations are lazy and which are not, which may not always be possible. Also if there is a slow and a fast consumer on a queue for a long time, and the slow consumer only acks intermittently, you still have the same problem. Instead what we need to do is create a compactor. The compactor is an extension of the reclaimer. Files can be marked as "tocompact" by the compactor if more than X% of the file is not needed. A separate compactor thread then checks the "tocompact" flag and compacts multiple files into smaller number -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
