Oct 09, 2025: Snowflake Data Clean Rooms updates

Clean Rooms API Version: 10.4

The following new features, enhancements, and fixes are now available in Snowflake Data Clean Rooms:

Features and enhancements:

  • The clean rooms UI now supports linking external and Apache Iceberg™ tables into a clean room. Previously, linking External Tables or Iceberg tables in the UI would result in failure of the clean room; now linking these table types in the UI is supported.

  • Reference usage grants update: You can now include a dataset with a Snowflake policy defined in a different database than the source. To do so, you must grant your clean room access to that policy database to be able to link the data into a clean room.

  • Autodetection of modified or removed data sources: If a data source becomes unavailable after a clean room is created or configured, the edit flow in the UI now prompts the user to pick from a current list of available data objects and prompts for removal of unavailable data sources.

Fixes:

  • If a clean room has a template that depends on a dataset that has become unavailable, previously the analysis would fail, and the clean room would become unusable in the UI. Now the template remains available, but the user is prompted to update the clean room to replace the missing dataset.
