Package org.apache.flink.runtime.state.v2

Class AbstractMapState<K,​N,​UK,​V>

  • Type Parameters:
    K - The type of partitioned key the state is associated to.
    UK - The type of user key of this state.
    V - The type of values kept internally in state.
    All Implemented Interfaces:
    org.apache.flink.api.common.state.v2.MapState<UK,​V>, org.apache.flink.api.common.state.v2.State, InternalKeyedState<K,​N,​V>, InternalMapState<K,​N,​UK,​V>, InternalPartitionedState<N>
    public class AbstractMapState<K,​N,​UK,​V>
extends AbstractKeyedState<K,​N,​V>
implements InternalMapState<K,​N,​UK,​V>
    A default implementation of MapState which delegates all async requests to StateRequestHandler.
