Hi @tonycox , i want to appologize first for opening another "project
pushdown" issue when this one is still in active. We actually come up with some
whole new idea and designs compare to the original design here, so we think
maybe it will be easier to open another pull request and let's discuss with
some codes.
But i noticed that this PR is becoming more similar with our design now
(only some slightly differences), even some core codes are copied from our pull
request. I think we should work out a plan to merge our work together.
A litter opinion here: I think it's pointless to let CsvTableSource be a
ProjecableTableSource since it simply cannot avoid reading extra fields in the
first place.
