[jira] [Created] (FLINK-14004) Define SourceReader interface to verify the integration with StreamOneInputProcessor

--------------------------------

             Summary: Define SourceReader interface to verify the integration with StreamOneInputProcessor
                 Key: FLINK-14004
                 URL: https://issues.apache.org/jira/browse/FLINK-14004
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Task
            Reporter: zhijiang
            Assignee: zhijiang


We already refactored the task input and output sides based on the new source characters in FLIP-27. In order to further verify that the new source reader could work well with the unified StreamOneInputProcessor in mailbox model, we would design a unit test for integrating the whole process. In detail:
 * Define SourceReader and SourceOutput relevant interfaces based on FLIP-27

 * Implement an example of stateless SourceReader (bounded sequence of integers)

 * Define SourceReaderOperator to integrate the SourceReader with StreamOneInputProcessor

 * Define SourceReaderStreamTask to execute the source input and implement a unit test for it.
