             Summary: Broadcast operation is not required when no parameters are specified
                 Key: SPARK-44305
                 URL: https://issues.apache.org/jira/browse/SPARK-44305
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: 7mming7


The ability introduced by SPARK-14912, we can broadcast the parameters of the data source to the read and write operations, but if the user does not specify a specific parameter, the propagation operation will also be performed, which affects the performance has a greater impact, so we need to avoid broadcasting the full Hadoop parameters when the user does not specify a specific parameter
