zhijiangW commented on issue #9905: [FLINK-14396][network] Implement rudimentary non-blocking network output URL: https://github.com/apache/flink/pull/9905#issuecomment-544371931 Thanks for the review @pnowojski . I have updated the codes for addressing above concerns. Only left one issue of providing non-blocking request from global `NetworkBufferPool`, and I think it is better to be done separately together with adjusting backpressure monitor later. Because when we provide `NetworkBufferPool#isAvailable` to avoid `availableMemorySegments.wait(2000);` in `LocalBufferPool`, it would destroy the exiting monitor of backpressure. And now this PR could still keep the previous behavior of backpressure monitor.
