Abstract

The invention discloses a data aggregation method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining initial data, and writing the initial datainto a source storage pool; reading a plurality of pieces of to-be-aggregated data from the source storage pool; aggregating the to-be-aggregated data to obtain aggregated data; writing the aggregated data into a target storage pool, and updating metadata corresponding to each piece of to-be-aggregated data; after the initial data is obtained, the initial data is not immediately aggregated, but is firstly written in and read out when aggregation is needed. If a cache failure fault occurs when the to-be-aggregated data is read out and waits for aggregation processing, or the cache failure fault occurs in the aggregation processing process, the to-be-aggregated data is written into the source storage pool, so that the problem of data loss does not occur.

Description

technical field [0001] The present invention relates to the technical field of data aggregation, in particular to a data aggregation method, a data aggregation device, a data aggregation device, and a computer-readable storage medium. Background technique [0002] In the era of big data, there are more and more massive data, and there are more and more applications for reading and writing small files with a size of a few K or more than a dozen K. In order to reduce the pressure of reading and writing data on the disk, the speed of using the disk to read and write large files is often significantly higher than the principle of small files. Related technologies do not directly write small files (such as a few K or more than a dozen K) Write to the cache first, wait in the cache and merge it into a large file (for example, the size is M level) before performing the disk operation, so as to improve the read and write speed of subsequent file reads and writes, and reduce the pres...
