-Because the fare events can arrive out of order, it will sometimes be
necessary to process events
-for one hour before having finished computing the results for the previous
hour. In fact, if the
-watermarking delay is much longer than the window length, then there may be
many windows open
-simultaneously, rather than just two. This implementation supports this by
using a `MapState` that
-maps the timestamp for the end of each window to the sum of the tips for that
window.
+由于票价事件（fare-event）可能会乱序到达，有时需要在计算完前一小时的结果之前处理一小时的事件。
+实际上，如果 Watermark 延迟比窗口长度长得多，则可能有多个窗口同时打开，而不仅仅是两个。
+此实现通过使用 `MapState` 来支持处理这一点，该 `MapState` 将每个窗口的结束时间戳映射到该窗口的 tips

I have translated the 'tips' into Chinese.
