Abstract

The invention discloses a data sampling method and device and a computer readable storage medium, and the method comprises the steps of sampling the data of a target type at a first sampling rate in a first time window, and obtaining the target sampling data; combining the target sampling data and the historical sampling data in the sampling database to obtain the combined sampling data, wherein the third sampling rate of the combined sampling data is determined according to the first sampling rate and the second sampling rate of the historical sampling data, and when the number of the combined sampling data is larger than a sampling number threshold value, sampling the combined sampling data based on the self-adaptive sampling parameters, and obtaining the updated historical sampling data, wherein the sampling number threshold value is related to the data of the target type; and the self-adaptive sampling parameter is used for controlling the quantity of the merged sampling data within a sampling quantity threshold value; and replacing the historical sampling data in the sampling database with the updated historical sampling data. By adopting the application, the system capacity can be saved when the data is sampled.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data sampling method, device and computer-readable storage medium. Background technique [0002] With the continuous development of computer networks, the amount of data generated in computer networks is increasing day by day. When it is necessary to perform big data statistical analysis on the full amount of data in the computer network, first of all, it is necessary to sample and count the full amount of data, and then through The data obtained by sampling and statistics is used to represent the full amount of data, for example, the data characteristics of the data obtained by sampling and statistics can be used as the data characteristics of the full amount of data. [0003] In the prior art, when it is necessary to sample the data generated within a certain time period, it is usually necessary to read all the data within the time period in advance, and...
