Embodiment 1

[0071] When the main cluster server does not fail, the timing diagram of the normal process is as follows figure 2 shown.

[0072] S201. The front end sends the generated message to the main cluster server.

[0073] The main cluster server stores and processes the messages sent by the frontend.

[0074] S202. The front end sends the generated message to the message middleware cluster.

[0075] Messages are sent to the message middleware cluster in an asynchronous and low-latency manner, ensuring quasi-real-time performance.

[0076] S203, the consumption function module reads the messages in the message middleware cluster.

[0077] S204, the consumption function module sends the message to the slave cluster server.

[0078] Back up the front-end messages from the cluster server. The master cluster server and the slave cluster server regularly compare and verify data. When the data is found to be inconsistent after verification, the master cluster server data is synchroni...

Abstract

The invention discloses a disaster tolerance method, device and system of a cross-machine-room cluster based on an HBase database and a computer readable medium. The method comprises the steps that afront end writes a message into a main cluster server; the front end sends the message to a message middleware cluster, a consumption function module consumes the message in the message middleware cluster, and the consumption function module writes the message into a slave cluster server; and the front end reads the state from the main cluster server, if the state reading fails, the front end writes the message into the slave cluster server, the front end sends the message to the message middleware cluster, and the consumption function module reads the message and writes the message into the main cluster server. Messages can be transmitted to the message middleware cluster in an asynchronous and low-delay mode at the bottom layer, the message middleware cluster sends the messages to the slave cluster servers, the quasi-real-time performance of cross-machine room data is guaranteed, meanwhile, master-slave cluster server data comparison and inspection are conducted regularly, and the final consistency of the data is guaranteed.

Description

technical field [0001] The present invention relates to the field of computer information processing, in particular to a disaster recovery method, device and system based on HBase database across computer room clusters. Background technique [0002] With the development of Internet finance, Internet financial services are increasingly dependent on data. In order to ensure the accuracy and security of data, disaster recovery technology is usually adopted. [0003] The current disaster recovery technology adopts the disaster recovery technology of computer room cluster servers, and usually writes data to the master cluster server and saves data at the same time as the slave cluster server. When the master cluster server fails, switch to the slave cluster server for data preservation. [0004] However, due to the high complexity of the cluster server in the computer room, the large front-end message throughput, and network delay, the data from the cluster server may be incomp...
