All Known Implementing Classes:

IndexedInputGate, InputGateWithMetrics, SingleInputGate, StreamTaskExternallyInducedSourceInput, StreamTaskFinishedOnRestoreSourceInput, StreamTaskSourceInput

@Internal
public interface CheckpointableInput

Input, with just basic methods for blocking and resuming consumption. It can be for example an InputGate or a chained source.
