[jboss-jira] [JBoss JIRA] Reopened: (JBMESSAGING-1289) Implement fast journal

Implement fast journal ---------------------- Key: JBMESSAGING-1289 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1289 Project: JBoss Messaging Issue Type: Task Reporter: Tim Fox Assigned To: Tim Fox Fix For: 2.0.0 Alpha Implement an extremely fast append only journal to be used as the primary form of persistence in JBoss Messaging. The journal should be able to run in one of two modes: a) Using pure Java NIO - this runs on any operating systems for which there is a Java 5 JRE. b) Using Linux asynchronous IO. This will only run on Linux kernel >= 2.6. But should give superior performance. The journal will auto-detect whether it is running on Linux and switch to asynch IO automatically, This can also be overrridden in the config. The journal fully supports transactions and XA. And can be used to append, update or delete arbitrary records. It has potentially to be re-used in other applications other than messaging.
