Package org.apache.flink.state.api.runtime

Class SavepointRuntimeContext

  • All Implemented Interfaces:
    org.apache.flink.api.common.functions.RuntimeContext
    @Internal
public final class SavepointRuntimeContext
extends Object
implements org.apache.flink.api.common.functions.RuntimeContext
    A streaming RuntimeContext which delegates to the underlying batch RuntimeContext along with a specified KeyedStateStore.

    This RuntimeContext has the ability to force eager state registration by throwing an exception if state is registered outside of open.
