Message queue system and method for realizing message communication

Abstract

Provided are a message queuing system and a method of realizing message communication. The system comprises: a first buffer area (21), a second buffer area (22) and a persistent storage (23). The first buffer area (21) and the second buffer area (22) are located in a memory of a server in which a message producer and a message consumer are located. The second buffer area (22) comprises a primary buffer area (221) and a secondary buffer area (222). The first buffer area (21) is configured to buffer a message pushed by the message producer, store the message in the persistent storage (23), and send the message stored in the persistent storage (23) to the second buffer area (22). The persistent storage (23) is configured to persistently store the message sent by the first buffer area (21). The secondary buffer area (222) is configured to buffer the message sent by the first buffer area (21). The primary buffer area (221) is configured to deliver the message therein to the message consumer, and after all of the messages is delivered to the message consumer, perform primary-secondary switching with the secondary buffer area (222). The system improves the real-time performance of message transmission in the message queuing system.

Description

Technical field[0001]This application relates to the field of computers, in particular to a message queue system and a method for realizing message communication.Background technique[0002]In computer systems, message queues are an important way to achieve communication between different processes or between different threads in the same process. In other words, different processes or different threads complete the message transmission in the message queue.[0003]In the existing related technologies, there have been a variety of implementation solutions for the message queue system. One of the solutions is that the message queuing system consists of a buffer area on the server where the process (or thread) is located and a local disk. Among them, the message pushed by the message producer is first stored in the cache area, and when the number of messages in the cache area reaches the configured value or the publishing time of the message exceeds the threshold, the messages in the cach...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the above technical problems, the embodiment of the present application provides a message queuing system and a method for realizing message communication, so as to solve the problems in the prior art that the real-time transmission of messages in the message queuing system is affected because the memory does not support simultaneous execution of read / write operations. sexual problems

In addition, it further solves the problem in the prior art that overflowed messages cannot be normally delivered to message consumers due to memory overflow in the message queue system
