> 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.
