Review comment:
Great idea, modified to override `createInsertStatementStr` to avoid
reassigning base class fields in the child class

> We only support {{insertion}} of new values into tables, not
> {{{}update/upsert{}}}. If you run an ingestion job with a record containing a
> record with the same primary key the whole job will fail because of the
> duplicate entry. We don't expect ingestion jobs to always contain _only new_
> records, so we should handle duplicate entries, ingestion of data already in
> the table or updates to old values. The insert vs. replace logic should be
> configurable to the user as well.
