-The first call, `.timeWindow()`, specifies that we want to have tumbling
(non-overlapping) windows
-of five seconds. The second call specifies a *Aggregate transformation* on
each window slice for
-each unique key. In our case we start from an initial value of `("", 0L)` and
add to it the byte
-difference of every edit in that time window for a user. The resulting Stream
now contains
-a `Tuple2<String, Long>` for every user which gets emitted every five seconds.
+首先调用 `.timeWindow()` 方法指定五秒翻滚(非重叠)窗口。第二个调用方法对于每一个唯一关键字指定每个窗口片`聚合转换`。
+在本例中，我们从`(""，0L)`初始值开始，并将每个用户编辑的字节添加到该时间窗口中。对于每个用户来说，结果流现在包含的元素为
`Tuple2<String, Long>`，它每5秒发出一次。
-The only thing left to do is print the stream to the console and start
execution:
+唯一剩下要做的就是将打印流输出到控制台并开始执行:
