-This section describes how the parallel execution of programs can be configured in Flink. A Flink
-program consists of multiple tasks (transformations/operators, data sources, and sinks). A task is split into
-several parallel instances for execution and each parallel instance processes a subset of the task's
-input data. The number of parallel instances of a task is called its *parallelism*.
-
-If you want to use [savepoints]({{ site.baseurl }}/ops/state/savepoints.html) you should also consider
-setting a maximum parallelism (or `max parallelism`). When restoring from a savepoint you can
-change the parallelism of specific operators or the whole program and this setting specifies
-an upper bound on the parallelism. This is required because Flink internally partitions state
-into key-groups and we cannot have `+Inf` number of key-groups because this would be detrimental
-to performance.
+本节描述了如何在 Flink 中配置程序的并发执行。一个 Flink 程序由多个任务 task 组成（转换/算子、数据源和数据汇）。一个 task 包括多个并发执行的实例，且每一个实例都处理 task 输入数据的一个子集。一个 task 的并发实例数被称为该 task 的 *parallelism*。
 
 Review comment:
   Hi 我个人认为此处parallelism应该翻译，它和其他名词没有任何区别（我个人连task也会翻译）。关于翻译成“并行度”还是”并发度“，我个人倾向前者。除了上面提到的英文单词的区别外，”并发“有一种被迫的感觉在里面，往往代表一些比较糟糕的情况，需要小心翼翼应对；而”并行“通常标识一种主动行为，词义偏向正面。总结下来就是我个人倾向于把parallelism翻译成”并行“。
