java.lang.Object

org.apache.flink.runtime.state.heap.StateTable<K,N,S>

org.apache.flink.runtime.state.heap.CopyOnWriteStateTable<K,N,S>

类型参数:

K - type of key.

N - type of namespace.

S - type of state.

所有已实现的接口:

Iterable<StateEntry<K,N,S>>, StateSnapshotRestore

public class CopyOnWriteStateTable<K,N,S>
extends StateTable<K,N,S>

This implementation of StateTable uses CopyOnWriteStateMap. This implementation supports asynchronous snapshots.
