-To guarantee end-to-end exactly-once record delivery (in addition to
exactly-once state semantics), the data sink needs
-to take part in the checkpointing mechanism. The following table lists the
delivery guarantees (assuming exactly-once
-state updates) of Flink coupled with bundled sinks:
+在精确一次状态语义的基础上，为了保证端对端精确一次的语义，sink 需要参与 checkpointing 机制。下表列举了 Flink 与其自带 sink
的交付保证（假设精确一次状态更新）。
Review comment:
I think "为了保证端到端精确一次的数据交付（在精确一次的状态语义上更进一步），sink需要参与快照机制。" is better.
