How to Query Cassandra Data in MySQL Workbench

You can use the SQL Gateway from the ODBC Driver for Cassandra to query Cassandra data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Cassandra data in MySQL Workbench.

Connect to Cassandra Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Cassandra data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Query Cassandra from MySQL Workbench

The steps below outline connecting to the virtual Cassandra database created in the SQL Gateway from MySQL Workbench and issuing basic queries to work with live Cassandra data.

Connect to Cassandra through the SQL Gateway

1. In MySQL Workbench, click to add a new MySQL connection.
2. Name the connection (CData SQL Gateway for Cassandra).
3. Set the Hostname, Port, and Username parameters to connect to the SQL Gateway.
4. Click Store in Vault to set and store the password.
5. Click Test Connection to ensure the connection is configured properly and click OK.

NOTE: When we refer to Username and Password, we mean the credentials for the user(s) created for the SQL Gateway.

Query Cassandra Data

1. Open the connection you just created (CData SQL Gateway for Cassandra).
2. Click File -> New Query Tab.
3. Write a SQL query to retrieve Cassandra data, like SELECT * FROM `CData Cassandra Sys`.Customer;

With access to live Cassandra data from MySQL Workbench, you can easily work with Cassandra, just like you would a MySQL database. Get started now with a free, 30-day trial of the CData ODBC Driver for Apache Cassandra and the CData SQL Gateway.
