Databricks Change Data Feed

Audience: Databricks Users

Content Summary: This page describes Immuta's support of Databricks Change Data Feed (CDF).


CDF shows the row-level changes between versions of a Delta table. The changes displayed include row data and metadata that indicates whether the row was inserted, deleted, or updated.

Immuta does not support applying policies to the changed data, and the CDF cannot be read for data source tables if the user does not have access to the raw data in Databricks. However, the CDF can be read if the querying user is allowed to read the raw data and one of the following statements is true:

  • the table is in the current workspace,
  • the table is in a scratch path,
  • non-Immuta reads are enabled AND the table does not intersect with a workspace under which the current user is not acting, or
  • non-Immuta reads are enabled AND the table is not part of an Immuta data source.
