Distributed message system and expansion method thereof

Abstract

The invention provides a distributed message system and an expansion method thereof. The system comprises a cluster resource monitoring module used for monitoring hardware resource use information of an agent side in real time and summarizing resource use standard exceeding rate of the agent side, and sending an expansion request when the resource use standard exceeding rate of the agent side reaches a threshold value; a cluster resource management module used for receiving the expansion request sent by the cluster resource monitoring module, calculating expansion required resources according to the expansion request and sending a resource equalization request; and a load balance notification module used for receiving the resource equalization request sent by the cluster resource management module, initiating resource change operation to a public address monitored by a message sending side and a message receiving side, and recording the expansion required resources in the public address. The system can realize automatic expansion.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a distributed message system and a capacity expansion method. Background technique [0002] Distributed message system service is a service that provides temporary storage of messages and distribution of messages on different computers at the same time. see figure 1 , is a schematic diagram of a distributed message system architecture. The entire system includes a message sending cluster 101, a proxy cluster 102, and a message receiving cluster 103, wherein the message sending cluster 101 includes a plurality of message sending terminals 1011, 1012, 1013..., proxy clusters 102 includes multiple agent terminals 1021, 1022..., and the message receiving terminal cluster 103 includes multiple message receiving terminals 1031, 1032, 1033.... The message sender (producer or Producer) constructs messages of different topics, and sends them to the agent (Broker) deployed with the mes...

AI Technical Summary

Problems solved by technology

This expansion method has at least the following defects: First, the operation and maintenance personnel need to observe the system load, and after confirming that the current distributed message system service may not be able to support the current load, then manually expand the computer resources of the message system cluster. There are errors in manual operation. secondly, the growth of future business volume is not an amount that can be accurately estimated, which may lead to frequent manual expansion operations; finally, every time a new service is added during the expansion process, a full cluster Load balancing, multiple load balancing may cause service instability
