[jira] [Created] (SPARK-27961) DataSourceV2Relation should not have refresh method

John Zhuge created SPARK-27961:
----------------------------------

             Summary: DataSourceV2Relation should not have refresh method
                 Key: SPARK-27961
                 URL: https://issues.apache.org/jira/browse/SPARK-27961
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: John Zhuge


The newly added `Refresh` method in PR #24401 prevented me from moving DataSourceV2Relation into catalyst. It calls `case table: FileTable => table.fileIndex.refresh()` while `FileTable` belongs to sql/core.

More importantly, [~rdblue] pointed out DataSourceV2Relation is immutable by design, it should not have refresh method.
