Manage the Trino Connector

This applies to: Visual Data Discovery

The Symphony Trino connector connects to a Trino server, and verified with versions 351-390. Trino is the new brand name for Presto.

You might use the Symphony Trino connector to connect to a Trino server on which the Trino connector is installed. After the connection is made, you would then be able to visualize and explore data in the PostgreSQL or AWS S3 database using the Symphony client.

The Trino connector has been validated and tested with PostgreSQL or AWS S3 databases only. Symphony cannot guarantee bug-free operation of the Trino connector with other databases, although you can try to use Trino to connect to them.

Before you can establish a connection from Symphony to the Trino server, the Trino connector server must be installed, configured and enabled. See Manage Connectors and Connector Servers for general instructions and Connect to Trino for details specific to the Trino 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 Visual Data Discovery 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 Data Discovery Dashboards.
