Apache Iceberg™ tables: Refreshing Delta-based tables fails if the UUID changes (Preview)¶

Attention

This behavior change is in the 2025_04 bundle.

For the current status of the bundle, refer to Bundle History.

For Delta-based Iceberg tables:

Before the change:: If the universally unique identifier (UUID) of the underlying Delta table changes, Snowflake doesn’t block refreshing the table.
After the change:: If the UUID changes, Snowflake recognizes the table as entirely separate and you can’t refresh it. If this occurs, recreate the Delta-based table.
