I just came across a page titled "What's up with Eclipselink?" and it mentions NoSQL. Tomorrow I will start a project using Cassandra, so that sounds interesting. Is there any information available about this NoSQL feature?

Hi Tom,

The NoSQL support is currently in development. You can take a look at the design doc and the tests that are checked into trunk in subversion at this point. We will be putting together some samples as development progresses.

Indeed using Cassandra's JDBC could work, although it naturally is not a relational schema, so probably native queries and the kinds should be used.

EclipseLink's NoSQL support is initially targeting Mongo DB and Oracle NoSQL. (both are operational in the trunk stream).

Cassandra is in our plans, but probably not for the 2.4 release.

Adding your own support by defining your own CassandraPlatform class and adapter is possible and should not be too difficult. We could provide any help required.

I know, I did some InformixPlatform as well. When I get to coding against Cassandra I'll see if putting Eclipselink in between makes sense. Still somewhat confused how that will fit in. Especially since I'm not picking Cassandra because I have small amounts of data.
