I think you only need to get one `RemoteInputChannel` for `requestSubpartition` and `onSenderBacklog` below. Another alternative way is you could construct `SingleInputGate` firstly, then construct relevant channel via `InputChannelBuilder#buildRemoteAndSetToGate(gate)`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
