[jira] [Created] (ARROW-10170) [Rust] [DataFusion] COUNT(*) schema name is COUNT(UInt8)

Jorge Leitão created ARROW-10170:
------------------------------------

             Summary: [Rust] [DataFusion] COUNT(*) schema name is COUNT(UInt8)
                 Key: ARROW-10170
                 URL: https://issues.apache.org/jira/browse/ARROW-10170
             Project: Apache Arrow
          Issue Type: Bug
          Components: Rust, Rust - DataFusion
            Reporter: Jorge Leitão


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.
