             Summary: SPJ: Introduce a new API for V2 input partition to report partition size
                 Key: SPARK-42040
                 URL: https://issues.apache.org/jira/browse/SPARK-42040
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.3.1
            Reporter: Chao Sun


It's useful for a {{InputPartition}} to also report its size (in bytes), so that Spark can use the info to decide whether partition grouping should be applied or not.
