Bucketing
Interfaces
Classes
- Bucket
- Buckets
- HashBucketing
- KeyGrouping
- Collects rows sharing a key into one batch, so a downstream operator sees each key exactly once and contiguously. The normalized hash is the key: no tuple, and `1`, `1.0` and `"1"` land together.
- KeyValues
- Extracts bucket-key values positionally, in reference order - position, not column name, defines key identity, so two sides of a join extract hash-compatible values from differently named columns.

- SingleBucketHasher

Enums
- BucketShape
