Distributed message system and expansion method

Abstract

The present invention provides a distributed message system and a capacity expansion method. The system includes: a cluster resource monitoring module, which is used to monitor the hardware resource usage information of the agent end in real time, and count the resource usage exceeding rate of the agent end. Send a capacity expansion request when the resource utilization rate at the end reaches a threshold; the cluster resource management module is used to receive the capacity expansion request sent by the cluster resource monitoring module, calculate the resources required for capacity expansion according to the capacity expansion request, and issue a resource balancing request; load balancing A notification module, configured to receive the resource balancing request sent by the cluster resource management module, initiate a resource change operation to the public addresses monitored by the message sending end and the message receiving end, and record the resources required for the expansion in the public address address. The invention can realize automatic capacity 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
