### Describe the usage question you have. Please include as many useful details as possible. I am still confused on the right way to use the hash aggregations. I found 3 different approaches in the hash_aggregation_test.cc which included a naive grouper/exec_plan and internal group_by. Is anyone particularly recommended as GroupBy is used in the python api but the doc said its not for public use. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
