Native connector for Cassandra using Crossdata.

Stratio Cassandra version 2.1 must be installed and started.
[Crossdata] (https://github.com/Stratio/crossdata) version 0.2.0-001 is needed to interact with this connector.

To automatically build execute the following command:

> mvn clean compile install

> mvn exec:java -Dexec.mainClass="com.stratio.connector.cassandra.CassandraConnector"

To generate the executable execute the following command:

> mvn crossdata-connector:install

To run Connector Cassandra execute:

> target/stratio-connector-cassandra-0.2.0/bin/stratio-connector-cassandra-0.2.0-001 start

To stop the connector execute:

> target/stratio-connector-cassandra-0.2.0/bin/stratio-connector-cassandra-0.2.0-001 stop

1. Start crossdata-server and then crossdata-shell.

2. https://github.com/Stratio/crossdata

3. Start Cassandra Connector as it is explained before

4. In crossdata-shell:

   Add a data store. We need to specified the XML manifest that defines the data store. The XML manifest can be found in the path of the Cassandra Connector in target/stratio-connector-cassandra-0.2.0/conf/CassandraDataStore.xml

   xdsh:user>  ADD DATASTORE <Absolute path to Cassandra Datastore manifest>;
   

   Attach cluster on that data store. The data store name must be the same as the defined in the data store manifest.

   xdsh:user>  ATTACH CLUSTER <cluster_name> ON DATASTORE <datastore_name> WITH OPTIONS {'Hosts': '[<ipHost_1, ipHost_2,...ipHost_n>]', 'Port': <cassandra_port>};
   

   Add the connector manifest. The XML with the manifest can be found in the path of the Cassandra Connector in target/stratio-connector-cassandra-0.2.0/conf/CassandraConnector.xml

   xdsh:user>  ADD CONNECTOR <Path to Cassandra Connector Manifest>
   

   Attach the connector to the previously defined cluster. The connector name must match the one defined in the Connector Manifest, and the cluster name must match with the previously defined in the ATTACH CLUSTER command.

   xdsh:user>  ATTACH CONNECTOR <connector name> TO <cluster name> WITH OPTIONS {'DefaultLimit': '1000'};
   

   At this point, we can start to send queries, that Crossdata execute with the connector specified.

   xdsh:user> CREATE CATALOG catalogTest;
   
   xdsh:user> USE catalogTest;
   
   xdsh:user> CREATE TABLE tableTest ON CLUSTER cassandra_prod (id int PRIMARY KEY, name text);
   
   xdsh:user> INSERT INTO tableTest(id, name) VALUES (1, 'stratio');
   
   xdsh:user> SELECT * FROM tableTest;
