Hi All Why does delta-sharing's change data feed API does NOT include table schema changes? For example, when a column is added to a delta table and delta-sharing's reference server's change data feed API is invoked, why we do not see metadata change event in the output?

I think the logic is that CDF captures row-level changes and the new row with the added column didn't change, Its schema is just different than rows from previous versions of the Delta Table. The parquet files containing the previously created rows in this additive schema change example also didn't change.
