[jira] [Created] (FLINK-19217) Functions repeated extend Serializable interface

darion yaphet created FLINK-19217:
-------------------------------------

             Summary: Functions repeated extend Serializable interface
                 Key: FLINK-19217
                 URL: https://issues.apache.org/jira/browse/FLINK-19217
             Project: Flink
          Issue Type: Improvement
            Reporter: darion yaphet


When I learning the functions, I found the Function interface have extend Serializable. But other Functions such as EdgesFunction, CoFlatMapFunction and MapFunction. they are all extends Serializable duplicate. Maybe it's unnecessary ? Could remove them ?
