I prefer to have a Jira (if that doesn't already exist) to translate this content to Chinese over just copying the English text to the Chinese document.


Flink 定期对每个算子的所有状态进行持久化快照，并将这些快照复制到更持久的地方，例如分布式文件系统。 如果发生故障，Flink 可以恢复应用程序的完整状态并恢复处理，就好像没有出现任何问题一样。

这些快照的存储位置是通过作业_checkpoint storage_定义的。
有两种可用检查点存储实现：一种持久保存其状态快照
到一个分布式文件系统，另一种是使用 JobManager 的堆。

The location where these snapshots are stored is defined via the jobs _checkpoint storage_.
Two implementations of checkpoint storage are available - one that persists its state snapshots
to a distributed file system, and another that users the JobManager's heap.
