Abstract

The invention discloses a machine room disaster tolerance control method, a terminal and a storage medium. The method comprises the steps that when a first user terminal detects a first cluster fault,a first instruction is generated, and the first instruction is used for indicating a second user terminal to obtain target storage information in a cache database; and the first instruction is sent to the second user terminal, so that the second user terminal reads a message from a message corresponding to the target storage information in the second cluster as a message reading starting site. According to the scheme, disaster tolerance processing is achieved when the main machine room breaks down, it is guaranteed that unprocessed backlog messages in an original main machine room cluster canstill be consumed continuously after the main machine room breaks down and is switched to the standby machine room, and the messages are basically not repeated.

Description

technical field [0001] The present application relates to the field of computer room disaster recovery, and in particular, relates to a computer room disaster recovery control method, a terminal and a storage medium. Background technique [0002] Kafka is a commonly used message queue middleware. For a system with high availability requirements, when it strongly relies on Kafka, if the computer room where Kafka is located fails, Kafka needs to provide cross-computer room disaster recovery capabilities. The current existing solution is to deploy two sets of Kafka clusters in two computer rooms respectively. When one computer room fails, the Kafka traffic in the faulty computer room is switched to the Kafka in the other computer room, and the business consumption Kafka server also consumes the other computer room. kafka. The problem with this solution is that if there is a backlog of kafka messages in the faulty computer room, when switching to another computer room, the back...
