Cassandra JDBC Driver

Connect Java applications with the Cassandra real-time NoSQL cloud database service. Use Apache Cassandra as the big data backend that powers your Java/J2EE applications.



Connect to Cassandra from wizards and query Cassandra data from the GUI in the RazorSQL database management tool.

The CData JDBC Driver for Cassandra enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to Cassandra using wizards in RazorSQL.

Create a JDBC Data Source for Cassandra Data

  1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
  2. In the Connection Wizard that appears, set the following properties:
    • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
    • Driver Class: Set the driver class to cdata.jdbc.cassandra.CassandraDriver.
    • Username: Enter the username. (This property can also be set in the JDBC URL.)
    • Password: Enter the password. (This property can also be set in the JDBC URL.)
    • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:cassandra: and is followed by a semicolon-separated list of connection properties.

      Set the Server, Port, and Database connection properties to connect to Cassandra. Additionally, to use internal authentication set the User and Password connection properties.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Cassandra JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.cassandra.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:cassandra:Database=MyCassandraDB;Port=7000;Server=127.0.0.1;

Query Cassandra Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
