On arrow2, I took the following approach: 1. Expose an `hash` kernel 2. use [`hash_hasher`](https://docs.rs/hash_hasher/2.0.3/hash_hasher/) My hypothesis is that if we move hashing to arrow instead of doing item by item, we likely gain a lot. However, to do that, we need to tell our hasher to not re-hash the keys that it receives, thus the `hash_hasher`. -- This is an automated message from the Apache Git Service.
