@viirya Maybe you have not read my discussion with @rdblue . @rdblue
already explained how Parquet internally works. Like what I said above, I think
we still need a test for confirming whether there does not exist a noticeable
extra penalty when no row is filtered out. Could you do a quick check based on
your existing test? Thanks!
