Interface | Description |
---|---|
AggregatingState<IN,OUT> |
State interface for aggregating state, based on an AggregateFunction . |
AppendingState<IN,OUT> |
Base interface for partitioned state that supports adding elements and inspecting the current
state.
|
BroadcastState<K,V> |
A type of state that can be created to store the state of a
BroadcastStream . |
CheckpointListener |
This interface is typically only needed for transactional interaction with the "outside world",
like committing external side effects on checkpoints.
|
InternalCheckpointListener |
The internal checkpoint listener add another
InternalCheckpointListener.notifyCheckpointSubsumed(long) interface
for internal usage. |
KeyedStateStore |
This interface contains methods for registering keyed state with a managed store.
|
ListState<T> |
State interface for partitioned list state in Operations. |
MapState<UK,UV> |
State interface for partitioned key-value state. |
MergingState<IN,OUT> |
Extension of
AppendingState that allows merging of state. |
OperatorStateStore |
This interface contains methods for registering operator state with a managed store.
|
ReadOnlyBroadcastState<K,V> |
A read-only view of the
BroadcastState . |
ReducingState<T> |
State interface for reducing state. |
State |
Interface that different types of partitioned state must implement.
|
ValueState<T> |
State interface for partitioned single-value state. |
