Abstract

The invention discloses a method and a system for determining TopN data, and equipment. The method comprises: executing grouping operation on original data according to name identifiers of data items,obtaining original data groups, and each name identifier corresponds to one original data group; for each original data packet, performing a deduplication operation according to a sorting field of adata item to obtain a deduplication data packet, and in the same original data packet, only retaining one of a plurality of data items with the same value of the sorting field in the same original data packet; for each duplicate removal data packet, executing in-group sorting operation on the data items based on the values of the sorting fields; and according to an operation result of the intra-group sorting operation, respectively determining data items of which the values of the sorting fields in each original data group are ranked at the first N bits.

Description

technical field [0001] This description relates to the field of computer technology, in particular to a method, system and equipment for determining TopN data. Background technique [0002] In the process of big data development, it is often necessary to determine the sorting of the dimension according to a certain dimension (the sorting here can be arranged from large to small or from small to large) of the top N data (N is a natural number, hereinafter referred to as is TopN data). In order to determine the TopN data, the usual practice is to perform grouping of the data first, and then perform intra-group sorting in each data group in a parallel processing manner, and finally determine the TopN data according to the sorting results of all data groups. This method of performing intra-group sorting on multiple groups in parallel greatly improves the data processing speed. [0003] The above-mentioned processing operation of performing parallel intra-group sorting on multi...
