Setting a tag for a specific column can be done using the SQL command:
https://docs.databricks.com/aws/en/sql/language-manual/sql-ref-syntax-ddl-set-tag

Is there another possible way to define a column tag?

For example, it is possible to add a column comment and masking function as below via the schema definition.

schema = """
Primary_Key BIGINT COMMENT "Primary Key",
Masked_Value STRING COMMENT "Masked Value" MASK catalog.schema.mask_function
"""

Hi @b-baran,
I couldn’t find any alternative in the official documentation — currently, the only supported way to define column tags is using ALTER TABLE ... ALTER COLUMN ... SET TAGS.
