When combined with CData Connect AI, it enables seamless access to Trello data for data virtualization, while also supporting data lineage and fine-grained access control.

This article explains how to use CData Connect AI to establish a live connection to Trello and how to access live Trello data from the Databricks platform.

CData Connect AI offers a seamless SQL Server, cloud-to-cloud interface for Trello, enabling you to effortlessly create dashboards and visualizations using live Trello data in Databricks. While building visualizations, Databricks requires SQL queries to retrieve the necessary data. With built-in optimized data processing, CData Connect AI pushes all supported SQL operations (such as filters and JOINs) directly to Trello, utilizing server-side processing for fast and efficient data retrieval of Trello data.

To work with Trello data in Databricks - Lakehouse Federation, you need to connect to Trello from Connect AI and provide user access to the connection.

👁 Adding a Connection

2. Select "Trello" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to Trello.

   Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

   Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

   • Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
   • OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.
