[GitHub] [spark] aniket486 commented on pull request #28649: [SPARK-31829] Check for partition existence before computation

aniket486 commented on pull request #28649:
URL: https://github.com/apache/spark/pull/28649#issuecomment-663347876


   Current implementation calls "[saveAsHiveFile](https://github.com/apache/spark/blob/master/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/InsertIntoHiveTable.scala#L205)" which triggers job to run the "select ... " query only to discard the output [later](https://github.com/apache/spark/blob/master/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/InsertIntoHiveTable.scala#L274) (by not calling externalCatalog.loadPartition)".
