I'm working (day job!) on a Java interface to the MySQL Cluster database (a.k.a. NDB). NDB is a high performance, high availability database used mostly in telecommunications applications. It can be the backing store for a MySQL server (accessed via any of the MySQL client APIs such as ODBC, JDBC)
or can be used directly via primitive C++ or Java APIs.

What I've been developing is a high performance, easy-to-use Java interface to NDB that bypasses the MySQL Server and instead goes directly to the native NDB API. I've used a Domain Object Model similar to Hibernate, JDO,
and JPA.

I'd like to work on this in Apache and would like to discuss the
opportunities with folks at ApacheCon. If this looks interesting, please let me know. I'll post a proposal to the incubator wiki if there is positive
feedback.

Interesting! However, I assume the MySQL side is all GPL. How does it
mix 'n match with the Apache License?

Yes, the MySQL Cluster code is currently licensed strictly as GPL/ Commercial. I'm working with the MySQL product folks on changing the license to be similar to the other MySQL connectors (waiving the GPL terms when used with approved open source licenses).

The plan is to license all of the ClusterJ code under the Apache license except for the code that actually invokes the NDB Cluster APIs (which is a very small part). That part would no be hosted at Apache, obviously.

Craig


Thanks,
