getInternalTimerService

public <N> InternalTimerService<N> getInternalTimerService(String name,
                                                           org.apache.flink.api.common.typeutils.TypeSerializer<K> keySerializer,

                                                           Triggerable<K,N> triggerable)

从接口复制的说明: InternalTimeServiceManager

Creates an InternalTimerService for handling a group of timers identified by the given name. The timers are scoped to a key and namespace.

When a timer fires the given Triggerable will be invoked.

指定者:

getInternalTimerService 在接口中 InternalTimeServiceManager<K>

advanceWatermark

public void advanceWatermark(Watermark watermark)

从接口复制的说明: InternalTimeServiceManager

Advances the Watermark of all managed timer services, potentially firing event time timers.

指定者:

advanceWatermark 在接口中 InternalTimeServiceManager<K>

snapshotToRawKeyedState

public void snapshotToRawKeyedState(org.apache.flink.runtime.state.KeyedStateCheckpointOutputStream context,
                                    String operatorName)
                             throws Exception

从接口复制的说明: InternalTimeServiceManager

Snapshots the timers to raw keyed state.

TODO: This can be removed once heap-based timers are integrated with RocksDB incremental snapshots.

指定者:

snapshotToRawKeyedState 在接口中 InternalTimeServiceManager<K>

抛出:

Exception
