[C++][Acero] Support for multi threaded input: ScalarAggregateNode , GroupByNode #47269
Closed as not planned
Description
Describe the enhancement requested
- Support for multi threading inputs (batches incoming not in order if they were ordered) with nodes like ScalarAggregateNode , GroupByNode and SortedMergeNode, previously resolved by disabling multi threading when using them.
- Propagating ordering information on output of nodes ScalarAggregateNode and GroupByNode when input is ordered.
I also created a PR with all the changes for this.
