>
> When {{RowLevelUpdateInfo#requiredColumns}} is specified to some columns
> (e.g., primary keys), sink function expects to receive the columns values
> including both the updated columns and primary key column. But sink function
> only receives the values of primary key columns, which makes update
> impossible without the updated columns.
