That's very reasonable. I'll send a PR for that after https://github.com/apache/parquet-format/pull/147 is checked in to avoid rebase racing. At that time, I'll also send a PR to support filters with sizes that are not a power of 2. I'll use https://lemire.me/blog/2016/06/27/a-fast-alternative-to-the-modulo-reduction/ to avoid the expensive modulo operation.
