----------------------------------

             Summary: Don't instantiate the class when loading by ServiceLoader
                 Key: SPARK-50897
                 URL: https://issues.apache.org/jira/browse/SPARK-50897
             Project: Spark
          Issue Type: Sub-task
          Components: Connect, ML
    Affects Versions: 4.0.0, 4.1.0
            Reporter: Bobby Wang


Currently, when tries to discovery the ml operators, spark connect needs to instantiate the all estimators/transformers/evaluators  by ServiceLoader every time which could cause a performance issue.
