[jira] [Created] (FLINK-13764) Pass the counter of numRecordsIn into the constructors of StreamOne/TwoInputProcessor

zhijiang created FLINK-13764:
--------------------------------

             Summary: Pass the counter of numRecordsIn into the constructors of StreamOne/TwoInputProcessor
                 Key: FLINK-13764
                 URL: https://issues.apache.org/jira/browse/FLINK-13764
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Task
            Reporter: zhijiang
            Assignee: zhijiang


Currently the counter of numRecordsIn is setup while processing input in processor. In order to integrate the processing logic based on StreamTaskInput#emitNext(Output) later, we need to pass the counter into output functions then.

So this refactoring is the precondition of following works, and it could get additional benefits. One is that we could make the counter as final field in StreamInputProcessor. Another is that we could reuse the counter setup logic for both StreamOne/TwoInputProcessors.

There should be no side effects if we make the counter setup a bit earlier than the previous way.
