-## Using Managed Operator State
+## 使用 Managed Operator State
-To use managed operator state, a stateful function can implement either the
more general `CheckpointedFunction`
-interface, or the `ListCheckpointed<T extends Serializable>` interface.
+用户可以通过实现 `CheckpointedFunction` 或 `ListCheckpointed<T extends Serializable>`
接口来使用 managed operator state。
#### CheckpointedFunction
-The `CheckpointedFunction` interface provides access to non-keyed state with
different
-redistribution schemes. It requires the implementation of two methods:
+`CheckpointedFunction` 接口提供了访问 non-keyed state 的方法，需要实现如下两个方法：
{% highlight java %}
void snapshotState(FunctionSnapshotContext context) throws Exception;
void initializeState(FunctionInitializationContext context) throws Exception;
{% endhighlight %}
-Whenever a checkpoint has to be performed, `snapshotState()` is called. The
counterpart, `initializeState()`,
-is called every time the user-defined function is initialized, be that when
the function is first initialized
-or be that when the function is actually recovering from an earlier
checkpoint. Given this, `initializeState()` is not
-only the place where different types of state are initialized, but also where
state recovery logic is included.
+进行 checkpoint 时会调用 `snapshotState()`。 用户自定义函数初始化时会调用
`initializeState()`，初始化包括第一次自定义函数初始化和从之前的 checkpoint 恢复。
+因此 `initializeState()` 不仅是定义不同状态类型初始化的地方，也需要包括状态恢复的逻辑。
-Currently, list-style managed operator state is supported. The state
-is expected to be a `List` of *serializable* objects, independent from each
other,
-thus eligible for redistribution upon rescaling. In other words, these objects
are the finest granularity at which
-non-keyed state can be redistributed. Depending on the state accessing method,
-the following redistribution schemes are defined:
+当前，managed operator state 已 list 的形式存在。这些状态是一个 *可序列*
对象的集合，彼此独立，方便在改变并发后进行状态的重新分派。
