Example for Using DataStax Enterprise Driver 1.1.x with Spring Data Cassandra 2.0.x

Using DataStax Enterprise Driver 1.1.x with Spring Data Cassandra 2.0.x

This repository provides a basic example of using the DataStax Enterprise Driver version 1.1.x with Spring Data Cassandra 2.0.x.

In particular, this demonstrates how to use a DSE-specific authenticator, which is provided in the DSE driver, with Spring Data.

This example follows the basic example in the spring-data-examples repository.

The main adjustment needed to use the dse-driver with spring-data-cassandra is to explicitly exclude cassandra-driver-core as a dependency of spring-data-cassandra. dse-driver is then defined as a separate dependency. This should allow the dse-driver to be used as a drop in replacement for cassandra-driver-core.

The second adjustment in this particular example is to override the getAuthProvider() method in the AbstractCassandraConfiguration to use DsePlainTextAuthProvider.

Setting up a Local DSE Node for Testing

To run the tests, you first need to set up a local DSE node that is preconfigured. The simplest way to accomplish this is to use ccm, but you may use an alternative means if you like. The following steps demonstrate how to set up a single-node DSE ccm cluster with authentication:

1. Create the ccm cluster (with username and password being that which you use to download DSE normally):

   ccm create -n 1 -v 5.0.7 --dse dse507_1 --dse-username=username --dse-password=password

2. Configure DSE to use authentication. In this particular case we use the internal authenticator which has a default cassandra user (with password cassandra), but you may use ldap or kerberos if appropriate:

   ccm updateconf authenticator:com.datastax.bdp.cassandra.auth.DseAuthenticator
   ccm updatedseconf authentication_options.enabled:true authentication_options.default_scheme:internal

3. Start the ccm cluster

   ccm start

4. Create the 'myks' keyspace

   ccm node1 cqlsh -e "create keyspace if not exists myks with replication={'class' : 'SimpleStrategy', 'replication_factor': 1}" -u cassandra -p cassandra

Running the Tests

With a single node CCM cluster set up, we can now run the tests to verify spring data is configured correctly. To do this simply run mvn verify. If everything goes well, the tests should pass and the output should look like:
