Description

During upsert, the primary key index is not properly maintained and is always empty. The problem is that when upserting secondary indexes, we generate new values and old values to clean up secondaries. However, since there is no secondary key for the primary key index, the old value would always points to the new primary key. As a result, LSMSecondaryUpsertOperator would always think the secondary key values do not change, ignoring maintaining the primary key index.
