### Describe the enhancement requested Observed while adding R support in https://github.com/apache/arrow/pull/44652. If you call this function on a Table/Dataset that has dictionary type columns (`factor` in R), you get ``` NotImplemented: Function 'hash_one' has no kernel matching input types (dictionary<values=string, indices=int8, ordered=0>, uint8) ``` It appears to have been left off in https://github.com/apache/arrow/pull/12368 and no followup issue was made. I don't see any technical reason for not doing it, but I'm not familiar enough with the C++ compute code to see how to add it. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
