Connect an External Catalog

Audience: Application Admins

Content Summary: This page outlines how to connect an external catalog from the App Settings page.

If you want to pull tags, column details, and data source details for your data sources, use the dbt Cloud integration.

Introduction

Immuta allows you to integrate external catalogs from different tools, including Alation, Collibra, or custom REST catalogs, each of which can be configured in the External Catalogs section of the App Settings page.

The primary purpose of connecting external catalogs and completing catalog integrations is to pull tags from the external table schemas. Immuta can ingest a data dictionary that you are already utilizing in an external catalog to help drive data policies.

Note that you will only be able to pull tags for queryable data sources.

Best Practice: External Catalog

Use a single catalog; having more than one can lead to multiple truths and data leakage.
