Ryan Blue commented on PARQUET-41:
----------------------------------
Sorry for the delay, [~Ferd], I'll have more feedback for you today.
[~jaltekruse], it isn't possible to remove a record from a bloom filter, unless
you recompute the filter without it. The k positions for each element overlap,
which is why you get a great size reduction. Unfortunately, that means you
can't unset one without possibly changing the inclusion judgement for all the
other inserted elements that overlapped that bit position.

> For row groups with no dictionary, we could still produce a bloom filter.
> This could be very useful in filtering entire row groups.
