Bug Explain
The bug is:
column_semantic_type
function to check and finds that it does not have this column, so it adds it to thecolumns_to_add
list.store_api::metadata::RegionMetadataBuilder::add_columns
). It ignores the request, does not add the column to the physical table, and does not return an error.Solution is to check physical region for actual
column_id
(and other metadata) to update to logical regionChecklist
