> 我认为，将CQ拆成send CQ（solicited_only=0）和recv CQ（solicited_only=1）这个方案，实现更简单、清晰、好维护。要通过交互来保证能poll到send WC，感觉实现比较复杂和不好保证没有bug。 其实 RDMA 滑动窗口机制就是通过交互来实现的， 只不过目前存在的缺陷是未有效防止发送端 SQ 耗尽。可以想一下， 如果不「将CQ拆成send CQ（solicited_only=0）和recv CQ（solicited_only=1）」 有没有可能存在一种情况，4 个窗口期去 poll CQE 都没有 poll 到一个 send CQE 呢？ -- This is an automated message from the Apache Git Service.
