Now system.iceberg_history shows history

Official CH changelog text
Now system.iceberg_history shows history for catalogs databases like glue or iceberg rest. Also renamed table_name and database_name columns to table and database in system.iceberg_history for consistency. #80975 (alesapin).
The system.iceberg_history table now shows history for catalogs databases such as Glue or Iceberg REST. Additionally, the columns table_name and database_name have been renamed to table and database, respectively, for improved consistency.

Why it matters

This feature enhances the system.iceberg_history table by supporting history tracking for catalog databases beyond the default Iceberg sources, like Glue or Iceberg REST catalogs. Renaming columns improves clarity and consistency, making it easier for users to query and understand historical metadata changes across multiple catalog types.

How to use it

Users can query the updated system.iceberg_history system table directly to view historical data across Glue, Iceberg REST, and other supported catalog databases. No additional configuration is required; users only need to adapt to the renamed columns table and database in their queries.
