For our purposes, it suffices to understand that asynchrony is introduced into a federated query plan by the optimizer's judicious placement of the TQ (Table Queue) operator.
就我们此处的目的而言，只要理解异步是通过优化器明智地放置TQ(表队列)操作符而引入到联邦查询计划之中的就足够了。
Federated asynchrony can be recognized in execution plans by the existence of the new ATQ (Asynchronous Table Queue) operator directly above SHIP operators corresponding to remote operations.
通过对应于远程操作的SHIP操作符上的AT Q (asynchronousTableQueue)操作符，可以识别执行计划中的联邦异步。
