[jira] [Created] (FLINK-23648) Drop StreamTwoInputProcessor in favour of StreamMultipleInputProcessor

Piotr Nowojski created FLINK-23648:
--------------------------------------

             Summary: Drop StreamTwoInputProcessor in favour of StreamMultipleInputProcessor
                 Key: FLINK-23648
                 URL: https://issues.apache.org/jira/browse/FLINK-23648
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Task
    Affects Versions: 1.14.0
            Reporter: Piotr Nowojski
            Assignee: Piotr Nowojski
             Fix For: 1.14.0


StreamTwoInputProcessor is less efficient and can be simply replaced with StreamMultipleInputProcessor. This also solves a performance problem for FLINK-23541, where initial version was causing a performance regression in two input processor, while multiple input was working fine. Hence instead of optimising StreamTwoInputProcessor, it's just simpler to drop it.
