Redash is a collaboration tool that lets you query, visualize, and share your data. When paired with
CData Connect AI, Redash gets access to live CockroachDB data. This article demonstrates how to connect to CockroachDB
using Connect AI and work with live CockroachDB data in Redash.
CData Connect AI provides a pure SQL Server interface for CockroachDB, allowing you to query data from
CockroachDB without replicating the data to a natively supported database.
Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations
(filters, JOINs, etc.) directly to CockroachDB, leveraging server-side processing to return the
requested CockroachDB data quickly.

Add a Personal Access Token

On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.

The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
