[jira] [Created] (SPARK-31154) Expose basic write metrics for InsertIntoDataSourceCommand

Lantao Jin created SPARK-31154:
----------------------------------

             Summary: Expose basic write metrics for InsertIntoDataSourceCommand
                 Key: SPARK-31154
                 URL: https://issues.apache.org/jira/browse/SPARK-31154
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0, 3.1.0
            Reporter: Lantao Jin


Spark provides interface `InsertableRelation` and the `InsertIntoDataSourceCommand` to delegate the inserting processing to a data source. Unlike `DataWritingCommand`, the metrics in InsertIntoDataSourceCommand is empty and has no chance to update. So we cannot get "number of written files" or "number of output rows" from its metrics.
