Alter Standard Table - Change Tracking

Modifies change tracking (CDC - Change Data Capture) settings. Change tracking records INSERT, UPDATE, and DELETE operations for streaming data integration.

Known limitations:

  • This change type does not support automatic rollback.

  • Snowflake snapshots created with Liquibase Secure 5.1 are incompatible with earlier versions due to enhanced object type detection for TABLES and VIEWS. Regenerate all snapshots with 5.1 after upgrading to avoid false differences in diff and diff-changelog operations.
