-## Tasks and Operator Chains
+## 任务和算子链
 
-For distributed execution, Flink *chains* operator subtasks together into *tasks*. Each task is executed by one thread.
-Chaining operators together into tasks is a useful optimization: it reduces the overhead of thread-to-thread
-handover and buffering, and increases overall throughput while decreasing latency.
-The chaining behavior can be configured; see the [chaining docs](../dev/stream/operators/#task-chaining-and-resource-groups) for details.
+分布式计算中，Flink 将算子（operator）的 subtask *链接（chain）*成 task。每个 task 由一个线程执行。把算子链接成 tasks 是一个很好的优化：它减少了线程间切换和缓冲的开销，并在降低延迟的同时提高了整体吞吐量。链接操作的配置详情可参考：[chaining docs](../dev/stream/operators/#task-chaining-and-resource-groups)
 
-The sample dataflow in the figure below is executed with five subtasks, and hence with five parallel threads.
+下图的 dataflow 由五个 subtasks 执行，因此具有五个并行线程。

   I don't think so too.
