-## Overview
+## 概述
+checkpoint使Flink的状态具有良好的容错性，通过checkpoint机制，Flink可以对作业的状态和计算位置进行恢复，因此Flink作业具备高容错执行语义。
-Checkpoints make state in Flink fault tolerant by allowing state and the
-corresponding stream positions to be recovered, thereby giving the application
-the same semantics as a failure-free execution.
+参考[Checkpointing]({{ site.baseurl
}}/dev/stream/state/checkpointing.html)查看如何在Flink程序中开启和配置checkpoint。
-See [Checkpointing]({{ site.baseurl }}/dev/stream/state/checkpointing.html)
for how to enable and
-configure checkpoints for your program.
+## 保留Checkpoint
-## Retained Checkpoints
-
-Checkpoints are by default not retained and are only used to resume a
-job from failures. They are deleted when a program is cancelled.
-You can, however, configure periodic checkpoints to be retained.
-Depending on the configuration these *retained* checkpoints are *not*
-automatically cleaned up when the job fails or is canceled.
-This way, you will have a checkpoint around to resume from if your job fails.
+checkpoint在默认的情况下仅用于恢复失败的作业，并不作保留，当程序取消时checkpoint就会被删除。当然，你可以配置周期性的策略来保留checkpoint。根据以下配置，这些保留的checkpoint在作业失败或取消时不会自动清除。这样，你就可以使用该checkpoint来恢复失败的作业。
