Problems solved by technology

By caching the written data in memory, it can solve the problem of disk IO twice for reading and writing request data, but it also brings greater memory overhead.
At the same time, if there is a high probability of a master-slave replica network partition, slave replica machine downtime and other abnormal conditions, a full synchronization needs to be triggered to ensure data consistency between the master and slave, which brings additional network bandwidth overhead

Abstract

The embodiment of the invention discloses a data multiplexing method and device, electronic equipment and a storage medium. The method comprises the following steps: storing a write-in request sent bya user through a synchronous log module; wherein the write-in request comprises current write-in data and a serial number of the current write-in data; storing the current write-in data into a current data file of a storage engine module, and performing hard link on the current data file to obtain a current shadow file corresponding to the current data file; establishing first index information of the currently written data in a synchronous log module according to the number of the currently written data and the current shadow file; and establishing second index information for the current write-in data in the storage engine module after the current write-in data is submitted. According to the embodiment of the invention, the synchronous log module and the storage engine module can reuseone piece of data, the writing pressure of a disk is reduced under the same writing QPS per second, the writing performance of a distributed storage system is improved, and the service life of storageequipment is prolonged.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a data multiplexing method, device, electronic equipment, and storage medium. Background technique [0002] A distributed storage system stores data dispersedly on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but also is easy to expand. [0003] A distributed storage system usually involves a synchronous log module and a storage engine mo...
