> where we strip all metadata columns
> That means:
> # Sink Upsert Materializer may produce shorter records (without metadata
> columns) - when retracting to a previous value, retrieved from state
> # Sink Upsert Materializer does not use metadata columns for equality
> comparison
> # Partitioning may not use the correct key columns, if the key columns are
> defineed after the metadata columns
> # Constraint validation is not applied for persisted metadata columns
