Review Comment:
I'm confused here, the Flink upsert job produces position deletes that
target the data files produced in the same commit, so how can we ignore the
deletes in the same commit when rewriting? Despite we can have later position
deletes, we can not ignore the position delete that has the same sequence
number.
