Ryan Blue commented on PARQUET-41:
----------------------------------
I just posted a google spreadsheet to back up the numbers in the above comment.
It has 2 pages:
1. Filter size compared to encoded data size by FPP and expected uniqueness
2. Effective FPP when a filter is overloaded
It would be great to have some people double-check those calculations and my
conclusions above.

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