Interface Summary

Interface	Description
CheckpointableInput	Input, with just basic methods for blocking and resuming consumption.

Class Summary

Class	Description
BufferManager	The general buffer manager used by InputChannel to request/recycle exclusive or floating buffers.
BufferOrEvent	Either type for Buffer or AbstractEvent instances tagged with the channel index, from which they were received.
ChannelStatePersister	Helper class for persisting channel state via ChannelStateWriter.
EndOfChannelStateEvent	Marks the end of recovered state of RecoveredInputChannel of this subtask or ResultSubpartition on the upstream.
GateBuffersSpec	The buffer specs of the InputGate include exclusive buffers per channel, required/total floating buffers and the target of total buffers.
IndexedInputGate	An InputGate with a specific index.
InputChannel	An input channel consumes a single ResultSubpartitionView.
InputChannel.BufferAndAvailability	A combination of a Buffer and a flag indicating availability of further buffers, and the backlog length indicating how many non-event buffers are available in the subpartition.
InputChannelID	Identifier for input channels.
InputGate	An input gate consumes one or more partitions of a single produced intermediate result.
InputGate.InputWithData<INPUT,DATA>	Simple pojo for INPUT, DATA and moreAvailable.
InputGateID	Runtime identifier of a consumed IntermediateResult.
InputGateSpecUtils	Utils to manage the specs of the InputGate, for example, GateBuffersSpec.
LocalInputChannel	An input channel, which requests a local subpartition.
LocalRecoveredInputChannel	An input channel reads recovered state from previous unaligned checkpoint snapshots and then converts into LocalInputChannel finally.
RecoveredInputChannel	An input channel reads recovered state from previous unaligned checkpoint snapshots.
RemoteChannelStateChecker	Handles the response of PartitionProducerStateProvider.
RemoteInputChannel	An input channel, which requests a remote partition queue.
RemoteRecoveredInputChannel	An input channel reads recovered state from previous unaligned checkpoint snapshots and then converts into RemoteInputChannel finally.
SingleInputGate	An input gate consumes one or more partitions of a single produced intermediate result.
SingleInputGateFactory	Factory for SingleInputGate to use in NettyShuffleEnvironment.
SingleInputGateFactory.ChannelStatistics	Statistics of input channels.
UnionInputGate	Input gate wrapper to union the input from multiple input gates.

Exception Summary

Exception	Description
PartitionConnectionException	Exception for failed partition requests due to connection failure with unreachable producer.
