This project has been discontinued in favour of [Stratio Crossdata](https://github.com/Stratio/Crossdata), which is a data federation system leveraging Apache Spark capabilities.
Native connector for Cassandra using Crossdata.
Get Cassandra Lucene Index plugin version 2.1.8 and put the jar generated into cassandra lib directory
Cassandra version 2.1.8 must be installed and started.
Crossdata version 0.5.0 is needed to interact with this connector.
Cassandra must be running in order to execute ITs. Otherwise, use -DskipITs To automatically build execute the following command:
> mvn clean compile install
> mvn exec:java -pl cassandra-connector -Dexec.mainClass="com.stratio.connector.cassandra.CassandraConnector"
To generate the executable execute the following command:
> cd cassandra-connector > mvn package -Ppackage
To run Connector Cassandra execute:
> target/stratio-connector-cassandra-0.4.1/bin/stratio-connector-cassandra-0.4.1 start
To stop the connector execute:
> target/stratio-connector-cassandra-0.4.1/bin/stratio-connector-cassandra-0.4.1 stop
It is possible too, to create a RPM or DEB redistributable package.
RPM and DEB Package:
> cd cassandra-connector > mvn package -Ppackage
Once the package it's created, execute this commands to install:
RPM Package:
> rpm -i cassandra-connector/target/cassandra-connector-0.4.1.noarch.rpm
DEB Package:
> dpkg -i cassandra-connector/target/cassandra-connector-0.4.1.all.deb
Now to start/stop the connector:
> service connector_cassandra start > service connector_cassandra stop
- Start crossdata-server and then crossdata-shell.
- Start Cassandra Connector as it is explained before
- In crossdata-shell ...
Attach cluster on a 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>};
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;
