Connect to Impala Data from Filemaker Pro (Mac)

FileMaker Pro is a cross-platform relational database application that allows users to visually modify a database. When paired with CData Connect AI, FileMaker Pro gets access to live Impala data. This article demonstrates how to connect to Impala using Connect AI and query Impala data in FileMaker Pro.

CData Connect AI provides a pure SQL Server interface for Impala, allowing you to query data from Impala 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 Impala, leveraging server-side processing to return the requested Impala data quickly.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
