CassandraItemReader, CassandraItemWriter & CassandraBatchlet have been implemented in jberet-support.  They will be formally available in the up-comming jberet 1.3.0.Final release.

CassandraItemReader, CassandraItemWriter & CassandraBatchlet are similar to their counter-parties in jdbc: JdbcItemReader, JdbcItemWriter & JdbcBatchlet, except for the following main differences:

* cassandra artifacts have different configuration batch properties than jdbc ones;

* unlike jdbc ones, cassandra artifacts do not have any dependencies on Jackson library;

* cassandra artifacts and jdbc artifacts are completely independent of each other.

To use any of the above cassandra batch artifacts, the only additional dependency is the datastax driver:

         <dependency>

            <groupId>com.datastax.cassandra</groupId>

            <artifactId>cassandra-driver-core</artifactId>

        </dependency>

For usage examples, see the following test apps:
