What changes were proposed in this pull request?
Parquet's AdaptiveBlockSplitBloomFilter is a technique for generating a bloom filter with the optimal bit size according to the number of distinct real data values. It may not come at no cost because it uses multiple BloomFilter candidates at runtime, which could increase CPU usage or time.
This pull request adds benchmark cases to compare with those that use the default BloomFilter size.
Why are the changes needed?
Improvement benchmark coverage for common user-orient features from parquet datasource
Does this PR introduce any user-facing change?
no
How was this patch tested?
benchmarking golden files attached
