### Descriptioin
The feature request is to support the Bloom Filter field type to optimize index storage. The use case for this feature is to create skipping indexes for raw datasets on S3. For exa…

Currently, our Parquet can use BloomFilter for any physical types. However, when BloomFilter apply on float:
1. What does +0 -0 means? Are they equal?
1. Should qNaN sNaN written in BloomFilter? Are …

**Summary**
We can use runtime filter's bloom index to do collision with parquet block's bloom filter index to do prune in storage level. When do parquet reading, we can improve filter chances.
