/**
 * An embedded, in-memory cassandra storage service that listens
 * on the thrift interface as configured in cassandra.yaml
 * This kind of service is useful when running unit tests of
 * services using cassandra for example.
 *
 * See {@link org.apache.cassandra.service.EmbeddedCassandraServiceTest} for usage.
 * <p>
 * This is the implementation of https://issues.apache.org/jira/browse/CASSANDRA-740
 * <p>
 * How to use:
 * In the client code simply create a new EmbeddedCassandraService and start it.
 * Example:
 * <pre>

        cassandra = new EmbeddedCassandraService();
        cassandra.start();

 * </pre>
