Distributed message system and service status detection method thereof

Abstract

The invention provides a distributed message system, which comprises a server, a client side and a zookeeper cluster, wherein the server comprises a server communication unit which is used for transmitting the starting information of a server progress to the zookeeper cluster; the zookeeper cluster comprises a node management unit which is used for creating a corresponding sub-node for the started server progress on the created root node, and the sub-node is a temporary node; the client side comprises a client side communication unit and a judgment unit, wherein the client side communication unit is used for acquiring the creation situation of the sub-node from the zookeeper cluster; and the judgment unit is used for judging the current usable service of the server according to the creation situation of the sub-node. The invention also correspondently provides a service status detection method of the distributed message system. Due to the adoption of the technical scheme of the invention, a highly available communication platform based on the zookeeper is established, so that the resource consumption of the server for the heartbeat detection can be reduced, and the vast expenditure problem of the management caused by the increased service can be fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a distributed message system and a service state detection method of the distributed message system. Background technique [0002] When writing distributed computing applications, "partial failure" often occurs, that is, when a message is transmitted between two nodes in the network, if a network error occurs, the sender cannot know whether the receiver has received the message or not. messages. The receiver may or may not have received the message before the network error occurred, or the receiving process may have died. The only way for the sender to get the truth is to reconnect to the receiver and send it a query. This is partial failure: we don't even know if an operation has failed. [0003] The current popular solution is mainly heartbeat detection, that is, the service provider and the consumer maintain a certain connection, and send heartbeat packets regularly t...

AI Technical Summary

Problems solved by technology

The disadvantage of this is that if the number of service consumers increases, the service provider will spend a lot on heartbeat detection, which will seriously affect the normal operation of the system.

[0004] Therefore, a new service status detection technology is needed, which can reduce the resource consumption of the server in heartbeat detection, and fundamentally solve the huge management overhead caused by the increase in services
