Poc: expose group hash feedback from GroupValues by Rachelint · Pull Request #23229 · apache/datafusion

Rachelint · 2026-06-29T01:09:25Z

Which issue does this PR close?

Part of hash aggregate repartition POC.

Rationale for this change

This POC prepares GroupValues for partition-aware partial aggregate output. The partial aggregate output path needs to know which input rows created new groups, and the hash for those rows, so it can later route newly-created group ids to target partitions without relying on a separate repartition + coalesce pipeline.

What changes are included in this PR?

Extend GroupValues::intern to fill per-row hashes and optionally return the input rows that created new groups.
Keep hash calculation inside GroupValues implementations.
Wire reusable hash/new-group-row buffers through aggregate hash table and row-hash paths.
Update existing call sites and benchmarks to the new intern signature.

Are these changes tested?

Yes:

cargo fmt --all
cargo clippy --all-targets --all-features -- -D warnings
cargo test -p datafusion-physical-plan group_values --lib
