ORM over Cassandra

I understand that currently GORA is under development for release of ORM over Cassandra/HBase.



Recently tried to develop some apps using Kundera.

It may be worth looking into:

http://code.google.com/p/kundera/.



IT is JPA complined annotation based framework.



For the same. recently it is extended for Support of ORM over HBase too.



Anybody aware of anything else?





Vivek

I don't know actually. But this[1] is intriguing me to try some tests
with myBatis over Cassandra.

Hi,
Kundera provides support for lucene based indexing and as well as second level cache support.
Not sure if it is there in GORA.
