代码片段对于seata的回复第二阶段的ACK消息，不需要处理失败的情况，如果失败，服务会ACK超时，会重新触发流程，重新给seata客户端发送第二阶段的回滚或者提交请求

我的疑问不是流程上的疑问，是代码上的疑问。 前面描述的两个代码片段中，片段1没有在入队失败情况下调用releaseCMD , 片段二 在失败情况下调用了releaseCMD， 两处不一样的原因是什么呢？

由于ACK不需要关注错误的情况，所以可以偷懒少写一点代码，对于正确性不产生影响。仅此而已。第二种情况，需要处理错误是因为需要调用callback，把错误告诉客户端。而 ACK的逻辑不需要回复客户端。

了解；可以统一下吧。要么都回收到sync.pool， 要么都不回收了得了。
P.S. 多谢解答
