### Describe the usage question you have. Please include as many useful details as possible. As I understand https://cloudxlab.com/blog/bucketing-clustered-by-and-cluster-by/ Hive supports "CLUSTERED BY (cols)" approach, where data are split into `0000<bucket>` files. Also Hive supports "PARTITIONED BY (cols)". In Arrow we have `arrow::dataset` that can be configured to write to different partitions like [this](https://arrow.apache.org/docs/cpp/dataset.html). I can't seem to find a way to write data, splitting them into relevant bucket-files. I guess, I need to define additional [custom] partitioning. But can't seem to find relevant hash function. Maybe somebody already walked that path and can share some insights (if not code)? ### Component(s) C++ -- This is an automated message from the Apache Git Service.
