When the calculations are completed on the partition, the values are passed back to the client, where the trivial aggregation calculation can be done.
当分区上的计算完成时，将值传回客户机，然后客户机可以执行简单的聚合计算。
Even the trivial case of a single partition can be used. However, the more partitions used, the better the calculation, for three reasons.
甚至可以使用单个分区的平凡的情况。
