Immuta v2021.4.0 Release Notes

Immuta v2021.4.0

Immuta version 2021.4.0 was released November 5, 2021.

v2021.4.0 New Features

General Availability

  • Databricks:

    • Change Data Feed: Immuta supports Change Data Feed (CDF), which 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.

    • Sparklyr Support

    • Databricks Runtime 8.4

    • Databricks Runtime 9.1: This runtime is only supported on Python/SQL clusters.

Public Preview

  • Approve to Promote: Approve to Promote allows users to create and review policies in a development environment before activating them on data sources in production environments. When this feature is enabled in a development instance of Immuta, any Global Policies that are created, edited, or staged will go through this approval process.

  • Native User Impersonation: Native impersonation allows users to natively query data in Snowflake, Redshift, Synapse, and Trino as another Immuta user.

  • Sensitive Data Discovery Improvements: This feature allows users to customize how sensitive data is detected and what tags are applied to that data.

  • Snowflake:

    • Snowflake as a Catalog: When enabled, Immuta automatically registers an external Snowflake catalog using the provided hostname and leveraging the Immuta System account that gets generated. Any Snowflake sources that are registered from that host will automatically have their relevant tags ingested into Immuta.

    • Snowflake Integration: Immuta manages and applies Snowflake row access and column masking policies on individual tables directly in Snowflake instead of creating views for Immuta data sources.

    • Snowflake Audit: Users can view audit records on the Immuta Audit page for queries run natively in Snowflake.

v2021.4.0 Deprecation Notice

  • BREAKING: Removed support for FTP data sources.
  • Policy Import/Export is deprecated and will be removed. This feature has been replaced with V2 of the Immuta API.
  • Support for HDFS data sources is deprecated.
