No doubts technical= ly both are possible but as I mentioned before I prefer to have a slim DAO.=

Hi Nirmallya,

You can try using Kundera (https://gi= thub.com/impetus-opensource/Kundera), a JPA 2.1 compliant Object-= Datastore Mapping Library for major NoSql datastores. It also supports Polyglot persistence out-of-the-box.


Thanks and regards,
Karthik.

You are probably better off using the driver as you = do not need an ORM. Cassandra is not a relational DB. You can find the docu= mentation here=C2=A0http://docs.datastax.com/en/developer/driver-matrix/doc/common= /driverMatrix.html. Pick the version that is applicable to your project.

Thanks,
