-This example implements a poor man's counting window. We key the tuples by the

+这个例子实现了一个简单的计数窗口。 我们把元组的第一个元素当作键（在示例中都键都是 "1"）。 该函数将出现的次数以及总和存储在 "ValueState"
中。
+一旦出现次数达到 2，则将平均值发送到下游，并清除状态重新开始。 请注意，我们会为每个不同的键（元组中第一个元素）保存一个单独的值。

-A *time-to-live* (TTL) can be assigned to the keyed state of any type. If a
TTL is configured and a

+任何类型的 keyed state 都可以有 *有效期* (TTL)。如果配置了 TTL 且状态值已过期，则会里最大可能清除对应的值，这会在后面详述。
-All state collection types support per-entry TTLs. This means that list
elements and map entries

+所有状态类型都支持单元素的 TTL。 这意味着列表元素和映射元素将独立到期。
-In order to use state TTL one must first build a `StateTtlConfig`
configuration object. The TTL

+在使用状态 TTL 前，需要先构建一个`StateTtlConfig` 配置对象。 然后把配置传递到状态描述符中启用 TTL 功能：
