Ferdinand Xu commented on PARQUET-41:
-------------------------------------
Hi,
I'm thinking about using the Bloom Filter API from Guava instead of
implementing it by our own. Any suggestions or comments?
[http://docs.guava-libraries.googlecode.com/git-history/release/javadoc/com/google/common/hash/BloomFilter.html#create(com.google.common.hash.Funnel,
int, double)]
Thank you!

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