1. Concept 1. Message middleware Message middleware can also be called message queue, which refers to the use of efficient and reliable message delivery mechanism for platform-independent data exchange, and the integration of distributed systems based on data communication. By providing message passing and message queuing models, process communication can be extended in a distributed […]

Message queue + how to ensure that messages are not lost + how to ensure the orderliness of messages + how to deal with message accumulation
1. Basic concepts of message queue The message queue model is divided into: queue model and publish/subscribe model. Introduction to the queue model: Producers send messages to queues. A queue can store messages sent by multiple producers, and a queue can also have multiple consumers. There is a competitive relationship between consumers, that is, each […]

This chapter will help you understand the basic principles of message queues; understand commonly used message middleware; understand RabbitMQ and its operating mechanism; and master the configuration of RabbitMQ as a message middleware. What is Spring Boot? Spring Boot is an open source framework provided by the Pivotal team that can simplify the creation and […]
How to use stack to implement queue in Python?
Queue and Stack are common data structures that are widely used in computer science. The stack is a Last-In-First-Out (LIFO) data structure, while the queue is a First-In-First-Out (FIFO) data structure. Generally, queue operations include enqueue and dequeue operations, while stack operations include push and pop operations. In Python, you can use a list to […]

C language stack and queue are a big gift package [stack implements queue, queue implements stack, and comes with a circular queue, ah ah ah ah]
Foreword [must read] Anyone who has learned stacks and queues is welcome to visit. . . [Baozi who has not learned it may not understand it well, because there are few comments and many implementations. [Mainly because of laziness (roll 0) 1. Implementation of stack Let’s build a stack Because the stack only operates on […]

An in-depth introduction to RabbitMQ: sequential consumption, dead letter queue and delay queue
1. RabbitMQ 1.1 Core Components RabbitMQ is an open source message middleware that implements the Advanced Message Queuing Protocol (AMQP) and provides various important components to support the production, transmission and consumption of messages. Producer: The producer is the sender of messages and is responsible for publishing messages to the RabbitMQ server. Messages can contain […]
Priority queue–priority_queue
Priority queue (priority_queue) The priority queue is a special queue. Like the general queue, it supports the first-in, first-out rule. However, unlike the general queue, it has its own unique storage style for the data it stores. priority_queue<int>pa; pa.push(1); pa.push(2); pa.push(3); pa.push(4); pa.push(5); int n = pa.size(); for (int i = 0;i <n;i + +) […]
