Abstract

The invention relates to a distributed data storage method and system, computer equipment and a storage medium. The method comprises the steps of obtaining a data writing request sent by a terminal, wherein the data writing request carries to-be-stored data; sending the data writing request to a main storage cluster for consistency verification; after the consistency verification is passed, synchronously storing the to-be-stored data to each main storage server in the main storage cluster; after the to-be-stored data is successfully written into each main storage server in the main storage cluster, generating a data synchronization instruction by utilizing the to-be-stored data; and sending the data synchronization instruction to the slave storage cluster, and asynchronously storing the to-be-stored data to each slave storage server in the slave storage cluster according to the data synchronization instruction. By adopting the method, the data storage efficiency can be effectively improved, and the data consistency can be kept.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a distributed data storage method, system, computer equipment and storage medium. Background technique [0002] With the rapid development of computer technology, the amount of data generated is also increasing. For example, with the development of enterprise business, the data that needs to be stored continues to increase, and the pressure on data storage is increasing. In a traditional method, the data to be stored is stored in a primary storage server and copied to one or more secondary storage servers for storage. Data replication from the master storage server to the slave storage server includes master-slave synchronous replication and asynchronous replication. However, the performance of the master-slave synchronous replication method is low, and the data consistency of the master-slave asynchronous replication is not high. Therefore, how to effectively impr...
