Dandandan opened a new issue #331: URL: https://github.com/apache/arrow-datafusion/issues/331
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Currently only primitive types and string types are supported as dictionary keys. For hash join and hash aggregate we need to hash values. **Describe the solution you'd like** Implement dictionary type in `create_hashes` function. **Describe alternatives you've considered** n/a **Additional context** Dictionary types are supported for group by now via `create_key_for_col`. There is an explicit check on using hash repartitioning for dictionary keys in the physical planner. This check can be removed when dictionaries are supported in `create_hashes`. -- This is an automated message from the Apache Git Service.
