Closing this draft after revisiting the scope. The main motivation was faster dictionary hashing, but those optimizations are tightly coupled to DataFusion’s hashing semantics and have since been implemented directly there. Bloom-filter support is already being developed in Parquet, and Theta sketches are available through Apache DataSketches, so a new top-level `arrow-hash` crate does not currently have a sufficiently distinct responsibility. Any reusable dictionary compaction or gather primitives can be proposed separately in the existing Arrow crates. -- This is an automated message from the Apache Git Service.
