The Java Broker does currently have a JDBC based store that uses Derby as the example implementation which works out of the box. IIRC you only need provide a different JDBC driver class if you want to change the actual DB used. That is of course if the new DB likes the SQL format. The only downside of it is that I know it hasn't had as much testing as the GPL'd BerkeleyDB Store. It is also severely lacking in documentation. Hopefully I can remedy some of that when looking at the store interfaces. Having a C++ persistent store would be fantastic, especially if it was cross platform. The current testing performed by ant test (and all its profile options) ignore any persistent testing. From a Java testing pov if we could write tests that worked with persistence and could be run against both C++ and Java brokers then that would do a lot for improving the robustness of our product.
