[jira] [Created] (SPARK-26975) Support nested-column pruning over limit/sample/repartition

Dongjoon Hyun created SPARK-26975:
-------------------------------------

             Summary: Support nested-column pruning over limit/sample/repartition
                 Key: SPARK-26975
                 URL: https://issues.apache.org/jira/browse/SPARK-26975
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Dongjoon Hyun


As SPARK-26958 shows the benchmark, nested-column pruning has limitations. This issue aims to remove the limitations on `limit/repartition/sample`. In this issue, repartition means `Repartition`, not `RepartitionByExpression`.
