Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] In view of the disadvantages of low calculation efficiency caused by the traditional quantile calculation method in the prior art, the embodiment of the present application provides a data processing method, which can effectively reduce the number of calculations and reduce the I / O operations on the disk, thereby increasing the efficiency of qu...

Abstract

Embodiments of the invention disclose a data processing method and apparatus. The method comprises the steps of obtaining multiple pieces of to-be-processed data; defining the to-be-processed data in a plurality of preset intervals; determining approximate values of the to-be-processed data in the intervals; and according to the approximate values, determining quantiles corresponding to the to-be-processed data. By utilizing the method and the apparatus, the approximate values are used for replacing the numerical values of the to-be-processed data defined in any interval, so that the quantity of data participating in a calculation process can be reduced. Therefore, the traversal frequency during quantile calculation can be reduced; the I / O operation on a database can be further reduced; and the efficiency of the quantile calculation process can be improved to a certain extent.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] With the development of information technology and the popularization of Internet technology, service providers (such as: websites, banks, telecom operators, etc.) need to process a huge amount of data. In actual application, the service provider may perform quantile calculations for some data according to business requirements (such as: data analysis). [0003] Among them, the quantile can be considered as the data corresponding to the quantile points that divide a set of ordered data into different parts. Specific example: In a set of ordered data, different data correspond to different values. Assume that the value of a certain data is 50. At the same time, suppose that in this set of data, the number of data with a value less than 50 The proportion is 70%, then the data with a value of 50 can be ...
