Abstract

The embodiment of the invention discloses a ranking analysis function processing method and device, electronic equipment and a storage medium, and the method comprises the steps: detecting that a target execution plan meets a preset ranking function optimization condition, and randomly distributing to-be-ranked data to a multi-thread system; performing preset ranking function processing on the to-be-ranked data to obtain initial ranking data, and deleting the initial ranking data according to preset ranking function data retention items to obtain initial deleted ranking data; summarizing the initial deletion ranking data to obtain middle ranking data, and distributing the middle ranking data to a plurality of threads; and performing preset ranking function processing on the middle ranking data according to the group information to obtain final ranking data, and deleting the final ranking data according to preset ranking function data retention items to obtain an execution result of the target execution plan. According to the method, the problem of high data distribution performance consumption in the data analysis process is solved, and the effect of effectively improving the performance of the analysis function in the processing process of the analysis function is achieved.

Description

technical field [0001] The embodiments of the present invention relate to data analysis technology, and in particular to a ranking analysis function processing method, device, electronic equipment, and storage medium. Background technique [0002] Various requirements often arise during data analysis, for example, student achievement rankings, performance rankings, etc. In the process of data analysis, the analysis function used is to calculate each group of data on the basis of grouping and return all rows in the group, which will cause the entire data to be distributed when the data volume is large. The distribution process is more complicated. [0003] Generally, in a multi-threaded system, the premise of parallelism between groups is that the data needs to be distributed, and the data of the same group is processed by the same thread. [0004] For the existing data analysis method, the entire data analysis process will lead to large performance consumption in the distr...
