[GitHub] [arrow-datafusion] jayzhan211 commented on issue #6555: Implement `unnest` function

   The return type of Unnest might be Vec<ArrayRef>, a set of rows (Vec) with an array of columns (Array). https://github.com/apache/arrow-datafusion/blob/9b419b19a66bdd35e9e5c0bca259786f8f3c3965/datafusion/expr/src/columnar_value.rs#L32-L38
   
   Maybe we can add another type like RowsOfArray(Vec<ArrayRef>) for the rows-based return type? Is there other alternative return types of Unnest?
