Problems solved by technology

[0003] The existing data reading method based on the distributed consensus protocol requires that each operation of reading data must follow the distributed consensus protocol (Raft protocol), that is, the service node that receives the data reading request sends the request through the network Send to other service nodes in the distributed system. After more than half of the service nodes in the distributed system confirm the data corresponding to the data read request, the data will be returned to the client, and it also needs to be recorded in the service node log, so that The overhead of reading data is too large, which affects the reading performance

Abstract

The invention discloses a data reading and writing method and a data reading and writing device based on the implementation of a distributed consistence protocol, computer equipment and a computer storage medium. The method comprises the steps of when any service node receives a data writing request sent by a first client, executing a data writing operation and updating a data version number recorded by the service node, and synchronizing data to be written to the other service nodes, and returning the data version number back to the first client; when any service node receives the data reading request carrying the first data version number sent by the second client, comparing the first data version number with the second data version number recorded by the service node, and responding tothe data reading request according to a comparison result. Therefore, the problem that in the prior art, when the data is read based on the distributed consistency protocol, the expense for reading the data is large due to the fact that more than half of the service nodes need to reach an agreement is solved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data reading and writing method, device, computing device and computer storage medium realized based on a distributed consensus protocol. Background technique [0002] A complete distributed system is formed by connecting many service nodes in different locations through the network, and a large amount of data is distributed among different service nodes in the entire network system. All clients connected to the distributed system can access the data in any service node. [0003] The existing data reading method based on the distributed consensus protocol requires that each operation of reading data must follow the distributed consensus protocol (Raft protocol), that is, the service node that receives the data reading request sends the request through the network Send to other service nodes in the distributed system. After more than half of the service nodes in the dis...
