Manage the MemSQL Connector

The Composer MemSQL connector lets you access the data available in MemSQL databases using the Composer client. The Composer MemSQL connector supports MemSQL versions 6.0 - 6.7.

Before you can establish a connection from Composer to MemSQL storage, a connector server needs to be installed and configured. See Manage Connectors and Connector Servers for general instructions and Connect to MemSQL for details specific to the MemSQL connector.

After the connector has been set up, you can create data source configurations that specify the necessary connection information and identify the data you want to use. See Manage Data Source Configurations for more information. After data sources are configured, they can be used to create dashboards and visuals from your data. See Create Dashboards.

Connect to MemSQL

The MemSQL connector requires a JDBC driver to be configured before you can connect to your data source.

1. Download and install the latest JDBC driver from https://dev.mysql.com/downloads/connector/j/. Instructions are provided on that web site.

2. After installing the driver, edit the MemSQL properties file and change the driver path and class name properties, as shown below and as described in Add a JDBC Driver:

   datasource.driver-config.class-name=com.mysql.cj.jdbc.Driver
   
   datasource.driver-config.jar-path=<JDBC_driver_filepath>
   

3. Save the properties file and restart the connector. See Add a JDBC Driver.
