-Every function and operator in Flink can be **stateful** (see [working with
state](state.html) for details).
-Stateful functions store data across the processing of individual
elements/events, making state a critical building block for
-any type of more elaborate operation.
+Flink 中的每个方法或算子都能够被**状态化**（阅读 [working with state](state.html) 查看详细）。
+状态化的方法在处理单个 元素/事件 的时候存储数据，让状态成为使各个类型的算子更加精细的重要部分。
+为了让状态容错，Flink 需要为状态添加**检查点（Checkpoint）**。检查点允许 Flink
恢复状态，并且能够在流中定位，让应用像无故障一样的运行。
Review comment:
checkpoint 建议不翻译
这句话的本意是：checkpoint使得flink能够恢复状态和在流中的位置，从而向应用提供和无故障执行时一样的语义
