[GitHub] [arrow-datafusion] yjshen opened a new issue, #2387: Re-organize and rename aggregates physical plan
yjshen opened a new issue, #2387:
URL: https://github.com/apache/arrow-datafusion/issues/2387
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
- We currently have a hash-based implementation, `GroupedHashAggregateStream` for aggregate with grouping keys, and a non-hash implementation for aggregate without grouping keys but named `HashAggregateStream`.
- We could further enrich the aggregation method from hash-based to sort-based at runtime when we are run out of memory, as described in https://github.com/apache/arrow-datafusion/issues/1570
**Describe the solution you'd like**
1. Promote `hash_aggregates` to a directory `aggregates`, and re-organize code inside this `aggregates` module.
2. Rename `HashAggregateExec` to `AggregateExec`, since it's not always hashing.
**Describe alternatives you've considered**
Don't move
