这里所描述的增强，其目的是将允许在大大扩展的环境中异步执行多个远程查询的查询计划引入到WFS V9.1中。
The purpose of the enhancements described here is to introduce query plans into WFS V9.1 that enable asynchronous execution of multiple remote queries in greatly expanded circumstances.
其主要动机是通过允许重叠处理提供数据给n - ary的操作符的远程查询，减少联邦查询所花费的时间。
Its primary motivation is to reduce the elapsed time of federated queries by enabling overlapped processing of remote queries that provide data to n-ary operators.
对于同时涉及本地表和远程（昵称）数据的查询，可以采用允许本地查询和多个远程查询片段并发和异步执行的执行计划。
Queries that involve both local tables and remote (nickname) data have the possibility of execution plans that allow concurrent and asynchronous execution of local and multiple remote query fragments.
同时涉及本地表和远程（昵称）数据的查询特别适合于允许本地和多个远程查询片段并发和异步执行的执行计划。
Queries that involve both local tables and remote (nickname) data are candidates for execution plans that allow concurrent and asynchronous execution of local and multiple remote query fragments.
因此，能从异步中获得最多好处的联邦查询是那些其远程查询比较复杂，在返回第一行数据之前需要花费较多时间的查询。
Thus, the federated queries which benefit the most from asynchrony are those whose remote queries are complex and and for which it is time consuming to return the first row.
如果您需要等待一个阻塞操作—比如，对于来自远程数据库查询的结果—您不会确切地知道在可以使用结果之前究竟要等待多长时间。
If you need to wait on a blocking action — say, the results from a remote database query — it is not clear exactly how long you will need to wait for results to be available.
查询在远程服务器上的编译，以及取足够的数据来填充union所有分支上的AT Q缓冲区，这两个过程是并行进行的。
