For example, in the previous query db2exfmt output, if you examine the details of the above DTQ (2) operator you will notice.

例如，在前面的查询db2exfmt输出中，如果检查d TQ(2)的细节，就会注意到。

This tells us that the output stream or results of the DTQ are flowing to a single coordinator partition, which implies that the cardinality at DTQ (2) does not need to be multiplied by 2.

这告诉我们，输出流(即dTQ的结果)流向一个协调器分区，这意味着DTQ(2)的基数不需要乘以2。
