-The naming convention of the state access methods contain its redistribution
-pattern followed by its state structure. For example, to use list state with the
-union redistribution scheme on restore, access the state by using `getUnionListState(descriptor)`.
-If the method name does not contain the redistribution pattern, *e.g.* `getListState(descriptor)`,
-it simply implies that the basic even-split redistribution scheme will be used.
 
-After initializing the container, we use the `isRestored()` method of the context to check
if we are
-recovering after a failure. If this is `true`, *i.e.* we are recovering, the restore logic
is applied.
+调用不同的获取状态对象的接口,会使用不同的状态分配算法。比如
`getUnionListState(descriptor)` 会使用 union redistribution 算法,
+而 `getListState(descriptor)` 则简单的使用 even-split redistribution 算法。
+
+当初始化好状态对象后,我们通过 `isRestored()` 方法判断是否从之前的故障中恢复回来,如果该方法返回
`true` 则表示从故障中进行恢复,会执行接下来的恢复逻辑。
 
-As shown in the code of the modified `BufferingSink`, this `ListState` recovered during state
-initialization is kept in a class variable for future use in `snapshotState()`. There the
`ListState` is cleared
-of all objects included by the previous checkpoint, and is then filled with the new ones
we want to checkpoint.
+正入代码所示,`BufferingSink` 中初始化时,恢复回来的 `ListState` 的所有元素会添加到一个局部变量中,供下次
`snapshotState()` 时使用。
