Abstract

The invention discloses a data storage method and a server applied to a distributed server cluster that includes multiple nodes. One embodiment of the method includes: receiving by the main node in the server cluster a data write-in request, wherein the data write-in request contains the data to be written in; broadcasting by the main node the data write-in request to each packet in the server cluster, wherein the each packet contains at least one node; responding by the main node to the confirmation information fed back by more than a half of the packets; sending to the user terminal initiating the data write-in request the notification information that the data are successfully written-in, wherein if the packets do not include the main node, the packet successfully writes the data to be written in the memory in response to at least one node in the packet and feeds back confirmation information to the main node. The embodiments of the invention can improve service availability while ensuring data consistency of the distributed data server cluster.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of database technology, and in particular to a data storage method and server applied to distributed server clusters. Background technique [0002] With the rapid growth of Internet data, databases, as the storage medium of Internet data, undertake more and more data storage and data access tasks. In a distributed data storage system, the same data has multiple copies stored in different servers. Data consistency is an important indicator of Internet services. Data consistency, that is, multiple copies of the same data are consistent. [0003] In the data consistency protocol adopted by the existing distributed data storage architecture, when the data is written to more than half of the servers, the data is considered to be written successfully. However, due to the limited server resources in the cluster, more server resources are occupied by data consist...
