cloneTable

Last updated: September 29, 2026

Creates a zero-copy clone of a Snowflake standard table with optional time travel support. Clones can be created from the current state or from a specific point in time within the retention window.

Known limitation: 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.
