Data storing method and device

Abstract

The invention discloses a data storing method and device. The data storing method includes the steps that time identification of data to be counted is obtained; the data to be counted are stored in different partitions of a database according to the time identification, wherein each partition corresponds to one piece of time identification; the data in the partitions storing the data to be counted are counted to obtain a statistical result; the statistical result is output. Through the data storing method and device, the problem that in order to ensure accurate storage of the data, system overhead is high is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data storage method and device. Background technique [0002] When performing statistical analysis on massive Internet data, it is necessary to store historical data statistics for a period of time (for example, accumulatively store data within 1 day), so as to quickly generate reports based on summarized data and avoid searching for original massive data , which is widely used in big data analysis. [0003] When data is stored in the existing technology, two schemes are usually adopted: one scheme is to store the historical data in multiple blocks, and once there is a delayed entry of historical data to be entered as new data, the delayed entry of historical data is stored separately as a block , and associate the historical data entered later with the historical data of the same period. Another solution is to delete all statistical data, and re-summarize historical da...
