                                    long sequenceId)
        Checks message checksum to retry if message was corrupted while sending to broker. Recomputes checksum of the message header-payload again.
        • if matches with existing checksum: it means message was corrupt while sending to broker. So, resend message
        • if doesn't match with existing checksum: it means message is already corrupt and can't retry again. So, fail send-message by failing callback
        参数:

      • verifyLocalBufferIsNotCorrupted

        protected boolean verifyLocalBufferIsNotCorrupted​(ProducerImpl.OpSendMsg op)
        Computes checksum again and verifies it against existing checksum. If checksum doesn't match it means that message is corrupt.
        参数:
        op -
        返回:
        returns true only if message is not modified and computed-checksum is same as previous checksum else return false that means that message is corrupted. Returns true if checksum is not present.
