[jira] [Created] (FLINK-23842) Add log messages for reader registrations and split requests.

Stephan Ewen created FLINK-23842:
------------------------------------

             Summary: Add log messages for reader registrations and split requests.
                 Key: FLINK-23842
                 URL: https://issues.apache.org/jira/browse/FLINK-23842
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.14.0


Currently, there are is nothing logged when source enumerators get reader registration events, or when they receive split requests.

While some specific source implementations log this in their implementation, for the general case, this information is missing, even though it is super valuable when debugging and understanding the work assignment behavior.
