[jira] [Created] (FLINK-11653) Add configuration to enforce custom UID's on datastream

Seth Wiesman created FLINK-11653:
------------------------------------

             Summary: Add configuration to enforce custom UID's on datastream
                 Key: FLINK-11653
                 URL: https://issues.apache.org/jira/browse/FLINK-11653
             Project: Flink
          Issue Type: Improvement
          Components: DataStream API
            Reporter: Seth Wiesman
            Assignee: Seth Wiesman


Current best practice when deploying Flink applications to production is to set a custom UID, using DataStream#uid, so jobs can resume from savepoints even if they job graph has been modified. Flink should contain a configuration that can allow users to fail submission if their program contains an operator without a custom UID; enforcing best practices similarly to #disableGenericTypes.
