Description
Based on performance study [https://docs.google.com/spreadsheets/d/1KCmmdgaFTWBmpOk9trePdQ2m6wPVj2G328fTcRnQP1M/edit?usp=sharing] we found that there is benefit in compressing bloom filters when storing in parquet. As this is an experimental feature, we will need to disable this feature by default.
