>
> During recovery process for unaligned checkpoint, the input channel state
> should also be recovered besides with existing operator states.
> The InputGate would request buffer from local pool and then interact with
> ChannelStateReader to fill in the state data. The filled buffer would be
> inserted into respective InputChannel queue for processing in normal way.
> It should guarantee that the new data from upstream side should not overtake
> the input state data to avoid mis-order issue.
