- <td>Delaying the retry means that after a failed execution, the
re-execution does not start immediately, but only after a certain delay.
Delaying the retries can be helpful when the program interacts with external
systems where for example connections or pending transactions should reach a
timeout before re-execution is attempted.</td>

<td>延时重试意味着执行遭遇故障后，并不立即重新启动，而是延后一段时间。当程序与外部系统有交互时延时重试可能会有所帮助，比如程序里有连接或者挂起的事务的话，在尝试重新执行之前应该等待连接或者挂起的事务超时。</td>

-For example:
+例如：
{% highlight yaml %}
restart-strategy.fixed-delay.attempts: 3
restart-strategy.fixed-delay.delay: 10 s
{% endhighlight %}
-The fixed delay restart strategy can also be set programmatically:
+固定延迟重启策略也可以在程序中设置：
<div class="codetabs" markdown="1">
<div data-lang="java" markdown="1">
{% highlight java %}
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
env.setRestartStrategy(RestartStrategies.fixedDelayRestart(
- 3, // number of restart attempts
- Time.of(10, TimeUnit.SECONDS) // delay
+ 3, // 尝试重启的次数
+ Time.of(10, TimeUnit.SECONDS) // 延时
));
{% endhighlight %}
</div>
<div data-lang="scala" markdown="1">
{% highlight scala %}
val env = ExecutionEnvironment.getExecutionEnvironment()
env.setRestartStrategy(RestartStrategies.fixedDelayRestart(
- 3, // number of restart attempts
- Time.of(10, TimeUnit.SECONDS) // delay
+ 3, // 尝试重启的次数
+ Time.of(10, TimeUnit.SECONDS) // 延时
))
{% endhighlight %}

-### Failure Rate Restart Strategy
+### 故障率重启策略
-The failure rate restart strategy restarts job after failure, but when
`failure rate` (failures per time interval) is exceeded, the job eventually
fails.
-In-between two consecutive restart attempts, the restart strategy waits a
fixed amount of time.
+故障率重启策略在故障发生之后重启作业，但是当**故障率**（每个时间间隔发生故障的次数）超过设定的限制时，作业会最终失败。
+在连续的两次重启尝试之间，重启策略等待一段固定长度的时间。
-This strategy is enabled as default by setting the following configuration
parameter in `flink-conf.yaml`.
+通过在 flink-conf.yaml 中设置如下配置参数，默认启用此策略。

感谢指正，我太粗心了，以后一定翻译得更细致。
