(v22) Manage the Vertica Connector

Manage the Vertica Connector

The Composer Vertica connector lets you access the data available in the Vertica SQL query engine using the Composer client. The Composer Vertica connector supports Vertica version 7.2.

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

The Vertica connector requires a JDBC driver to be configured before you can connect to your data source. You can download the driver from the vendor's site. If you are upgrading, keep in mind you need to configure the JDBC driver - see Upgrade Composer for instructions. For more information and steps, see Add a JDBC Driver .

Composer supports Flex tables. However, you must properly map the metadata for the Flex tables in Vertica to use these data in Composer.

The Interval data type in Vertica will be converted to the Number type in Composer. The values for the Interval data type will be converted as follows in Composer:

• INTERVAL [DAY TO SECOND] - number of seconds
• INTERVAL [YEAR TO MONTH] - number of months

The fields containing these converted data will be marked as Raw Data Only. You can view these data in the Details window on a visual or export as raw data .
