Hi folks,
How to change streaming table/column description in DLT during run time like we do for delta tables because ALTER STREAMING table isn't working.
eg:
COMMENT ON COLUMN ops_catalog_gld_dev.schema_silver.table_name.property_sid IS 'The key of the property of the message_2';
OR
ALTER TABLE main.telemetry_db.table_name SET TBLPROPERTIES ('comment' = 'Telemetry latency aggregation metrics across pipelines');

Modifying streaming table column descriptions should be done via pipeline configuration instead of runtime SQL commands, as DLT does not retain such runtime alterations during pipeline refreshes.

How do we do this? The only documentation I can see shows how to add a comment for the streaming table but not comments for column level.
