Review Comment:
   Or better, if we can fix the bulk_insert to be with the same behavior with 
insert, that would be great: implicitly to change bulk_insert into insert for 
multiple writes of bulk_insert.
   
   Because we are kind of assuming `INSERT` instead of `UPSERT` for multiple 
bulk_inserts.
