Trino

Trino is a distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. This article will cover how to connect to Trino from Noteable.

Prepare

You will need the following information to create the connection:
  • Host
  • Port (default 8080)
  • Catalog name
  • Username (and password, if required)
  • Whether the host uses HTTP/HTTPs
If your data source is behind a firewall, you will need to ensure your firewall accepts incoming connections from Noteable. Read more: Query external data​
