 当 checkpoint coordinator（job manager 的一部分）指示 task manager 开始 checkpoint 时，它会让所有 sources 记录它们的偏移量，并将编号的 _checkpoint barriers_ 插入到它们的流中。这些 barriers 流经 job graph，标注每个 checkpoint 前后的流部分。

 Checkpoint _n_ 将包含每个 operator 的 state，这些 state 是对应的 operator 消费了**严格在 checkpoint barrier _n_ 之前的所有事件，并且不包含在此（checkpoint barrier _n_）后的任何事件**后而生成的状态。
 
 当 job graph 中的每个 operator 接收到 barriers 时，它就会记录下其状态。拥有两个输入流的 Operators（例如 `CoProcessFunction`）会执行 _barrier 对齐（barrier alignment）_ 以便当前快照能够包含消费两个输入流 barrier 之前（但不超过）的所有 events 而产生的状态。

 Flink 的 state backends 利用写时复制（copy-on-write）机制允许当异步生成旧版本的状态快照时，能够不受影响地继续流处理。只有当快照被持久保存后，这些旧版本的状态才会被当做垃圾回收。
