External Catalog Introduction

Users who want to use tagging capabilities outside of Immuta and pull tags from external table schemas can connect Collibra or Alation as an external catalog. If users have another catalog, or have customized their Collibra or Alation integrations, they can connect through the REST Catalog using the Immuta API. Users can also connect a Snowflake account to allow Immuta to ingest Snowflake tags onto Snowflake data sources.

Once they have been connected, Immuta will ingest a data dictionary from the catalog that will apply data source and column tags directly onto data sources. These tags can then be used to drive governance policies or classification frameworks. Using existing metadata from external catalogs can allow users to scale policy creation quickly.

Supported external catalogs

Immuta supports the following external catalogs:

Custom REST catalog

If users have an unsupported catalog, or have customized their Collibra or Alation integrations, they can connect through the REST Catalog using the Immuta API.

For more details about using a custom REST catalog with Immuta, see the Custom REST Catalog Interface Introduction.

Snowflake tag ingestion

Users can connect a Snowflake account to allow Immuta to ingest Snowflake tags onto Snowflake data sources. To learn more about Snowflake tag ingestion, see the Snowflake reference guide.

External Catalog Behaviors

  • Tags ingested from external catalogs cannot be edited within Immuta. To edit, delete, or add a tag from an external catalog to a data source or column, make the change in the external catalog.
  • You can configure multiple external catalogs within a single tenant of Immuta, but only one external catalog can be linked to a data source.
