[jira] [Created] (FLINK-21315) Support to set operator names in state processor API

Jun Qin created FLINK-21315:
-------------------------------

             Summary: Support to set operator names in state processor API
                 Key: FLINK-21315
                 URL: https://issues.apache.org/jira/browse/FLINK-21315
             Project: Flink
          Issue Type: Improvement
            Reporter: Jun Qin


Currently, it is not possible to set a user-friendly operator name when using state processor API. For example, when you use `readKeyedState()`, the operator name shows on the Flink UI is: 

{{DataSource (at readKeyedState(ExistingSavepoint.java:282) (org.apache.flink.state.api.input.KeyedStateInputFormat))}}

The same long name is shown on Grafana when Flink metrics are displayed.  This Jira aims to provide users an option to set operator names in state processor API.
