Closing after further investigation. The dictionary-hashing improvements that motivated this proposal fit DataFusion’s query-engine-specific hashing path and have been implemented there. Bloom-filter work belongs with the existing Parquet implementation, while Theta sketches are already provided by Apache DataSketches. Without another concrete consumer requiring compatible row hashes, adding a new Arrow hashing crate and public hash-stability contract is not justified. Narrow reusable pieces such as dictionary compaction or primitive gather optimizations can be proposed separately in the relevant existing Arrow crates. -- This is an automated message from the Apache Git Service.
