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.

Start by locating Hudi's Parquet bloom-filter storage and configuration code, then identify how an experimental compression option can be disabled by default; done means the option works when enabled and leaves the default behavior unchanged.
