[GitHub] [arrow-datafusion] houqp commented on issue #1372: Support Sort on unprojected columns

   Doing a projection "push up" could be a quick workaround to enable this in datafusion. For example, in logical plan builder's `sort` method, we can detect whether any of the sort columns are missing in the input plan's schema, if not, we rewrite downstream projection plans by adding the missing sort columns, then add a new projection plan after the sort plan to remove the injected sort columns.
