Abstract

The invention discloses a data reading method and a data reading device based on the implementation of a distributed consistence protocol, computer equipment and a computer storage medium. The methodcomprises the steps of selecting a service node from a plurality of service modes to serve as a main service node, setting lease time of the main service node, and broadcasting node information of themain service node to the other service nodes; when any service node receives a data reading request sent by a client, and comparing the node information of the service node with the node informationof the main service node to determine that whether the service node is the main service node; and if the service node is not the main service node, forwarding the data reading request to the main service node, so as to return data stored by the main service node to a client. Therefore, the data reading efficiency and reading performance can be enhanced, and the problem that in the prior art, the overhead for reading the data is large is overcome.

Description

technical field

[0001] The present invention relates to the technical field of data processing, in particular to a data reading 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 distrib...

Embodiment Construction

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] figure 1 A schematic flowchart of a data reading method implemented based on a distributed consensus protocol according to an embodiment of the present invention is shown. This method is applied to a distributed system containing multiple service nodes, such as figure 1 As shown, the method includes the following steps:

[0027] Step S100, select a service node from multiple service nodes as the main service node, set the ...
