[jira] [Created] (FLINK-27206) Deprecate reflection-based reporter instantiation

Chesnay Schepler created FLINK-27206:
----------------------------------------

             Summary: Deprecate reflection-based reporter instantiation
                 Key: FLINK-27206
                 URL: https://issues.apache.org/jira/browse/FLINK-27206
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Metrics
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.16.0


Metric reporters can currently be instantiated in one of 2 ways:
a) the reporter class is loaded via reflection
b) the reporter factory is loaded via reflection/ServiceLoader (aka, plugins)

All reporters provided by Flink use the factory approach, and it is preferable because it supports plugins. The plugin approach also has been available 1.11, and I think it's fair to deprecate the old approach by now.
