Describe what's wrong
I have DataLakeCatalog database and Iceberg table in it.
I run:
ALTER TABLE glue.`clickhouse-regression-database-1.table_a` ADD COLUMN new_column UInt64And get:
Received exception from server (version 25.8.1):
Code: 49. DB::Exception: Received from localhost:9000. DB::Exception: Metadata is not initialized. (LOGICAL_ERROR)
Does it reproduce on the most recent release?
Yes
How to reproduce
- Create DataLakeCatalog database and Iceberg table
- Run ALTER TABLE query:
ALTER TABLE glue.`clickhouse-regression-database-1.table_a`
(ADD COLUMN `new_column` UInt64)Expected behavior
Code: 48. DB::Exception: Alter of type 'ADD_COLUMN' is not supported by storage Iceberg
