# 有状态流处理
-## What is State?
+## 什么是状态？
-While many operations in a dataflow simply look at one individual *event at a
-time* (for example an event parser), some operations remember information
-across multiple events (for example window operators). These operations are
-called **stateful**.
+虽然数据流中的很多操作一次只着眼于一个单独的事件（例如事件解析器），但有些操作会记住多个事件的信息（例如窗口算子）。
+这些操作称为**有状态的**（stateful）。
-Some examples of stateful operations:
+有状态操作的一些示例：
- - When an application searches for certain event patterns, the state will
- store the sequence of events encountered so far.
- - When aggregating events per minute/hour/day, the state holds the pending
- aggregates.
- - When training a machine learning model over a stream of data points, the
- state holds the current version of the model parameters.
- - When historic data needs to be managed, the state allows efficient access
- to events that occurred in the past.
+ - 当应用程序搜索某些事件模式时，状态将存储到目前为止遇到的事件序列。
Review comment:
event 事件
the sequence of events encountered so far ： 截止到当前事件序列
个人感觉就是：state记录了截止到当前所发生的事件.
sequence 这里不知道是翻译成按顺序记录，还是序列好理解。
可以群里问问他们大家一起聊聊，怎么理解才是对的
