I find this comment: https://github.com/apache/arrow-datafusion/blob/master/datafusion/optimizer/src/projection_push_down.rs#L98-L100 It says that `Ensure that we are reading at least one column from the table`. Is there any reason or background of why we need to do this? -- This is an automated message from the Apache Git Service.
