> Key: ARROW-10170
> URL: https://issues.apache.org/jira/browse/ARROW-10170
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust - DataFusion
> Reporter: Jorge Leitão
> Priority: Minor
>
> Currently, the query {{COUNT(*)}} is being converted to {{COUNT(1)}} during logical planning, which causes the field's name to be {{COUNT(1)}}, not {{COUNT(*)}}
> One idea is to delay the map for the physical planning, when naming is no longer an issue.
