The difference between swoole and rabbitmq
RabbitMQ is an open source message broker software (also known as message-oriented middleware) that implements the Advanced Message Queuing Protocol (AMQP).
RabbitMQ server is written in Erlang language, while clustering and failover are built on the Open Telecommunications Platform framework. All major programming languages have client libraries that communicate with proxy interfaces. (Recommended learning: swoole video tutorial)
RabbitMQ is a set of open source (MPL) message queue service software. It is an open source implementation of Advanced Message Queuing Protocol (AMQP) provided by LShift , written in Erlang, which is known for its high performance, robustness, and scalability.
Main features
Scalability: Cluster service
Message persistence: persist messages from memory to hard disk, and then load them from hard disk to memory
Swoole is a PHP C extension that can be used to develop PHP's high-performance and high-concurrency TCP/UDP Server.
Swoole's network IO part is based on the epoll/kqueue event loop and is fully asynchronous and non-blocking. The business logic part uses multi-process synchronous blocking mode to run. This ensures that the server can handle high concurrency and a large number of TCP connections. It also ensures that business code can still be written simply.
Asynchronous support has been added since Swoole 1.6.2, and applications can also write asynchronous callbacks like node.js.
Swoole is more powerful than Node.js and supports synchronous/asynchronous and multi-process parallelism. Swoole provides process life cycle management and memory protection mechanisms. Developers do not need to consider the underlying details and focus on business logic and functions. development.
Swoole has a built-in asynchronous non-blocking, multi-threaded network IO server at the bottom. PHP programmers only need to handle event callbacks and do not need to care about the underlying layer. Unlike fully asynchronous frameworks such as Nginx/Tornado/Node.js, Swoole supports both fully asynchronous and synchronous.
Swoole has supported built-in coroutines since version 2.0, and can use fully synchronous code to implement asynchronous programs. There is no need to add any additional keywords to the PHP code. The bottom layer automatically performs coroutine scheduling to achieve asynchronous implementation.
Swoole is open source and free software, and the licensing agreement is Apache2.0. Enterprises and developers can use Swoole's code for free, and modifications made on Swoole do not need to be open source.

How to use swoole coroutine in laravel
Apr 09, 2024 pm 06:48 PM
Using Swoole coroutines in Laravel can process a large number of requests concurrently. The advantages include: Concurrent processing: allows multiple requests to be processed at the same time. High performance: Based on the Linux epoll event mechanism, it processes requests efficiently. Low resource consumption: requires fewer server resources. Easy to integrate: Seamless integration with Laravel framework, simple to use.
How to use Swoole to implement a high-performance HTTP reverse proxy server
Nov 07, 2023 am 08:18 AM
How to use Swoole to implement a high-performance HTTP reverse proxy server Swoole is a high-performance, asynchronous, and concurrent network communication framework based on the PHP language. It provides a series of network functions and can be used to implement HTTP servers, WebSocket servers, etc. In this article, we will introduce how to use Swoole to implement a high-performance HTTP reverse proxy server and provide specific code examples. Environment configuration First, we need to install the Swoole extension on the server
How does swoole_process allow users to switch?
Apr 09, 2024 pm 06:21 PM
Swoole Process allows users to switch. The specific steps are: create a process; set the process user; start the process.
Which one is better, swoole or workerman?
Apr 09, 2024 pm 07:00 PM
Swoole and Workerman are both high-performance PHP server frameworks. Known for its asynchronous processing, excellent performance, and scalability, Swoole is suitable for projects that need to handle a large number of concurrent requests and high throughput. Workerman offers the flexibility of both asynchronous and synchronous modes, with an intuitive API that is better suited for ease of use and projects that handle lower concurrency volumes.
How to restart the service in swoole framework
Apr 09, 2024 pm 06:15 PM
To restart the Swoole service, follow these steps: Check the service status and get the PID. Use "kill -15 PID" to stop the service. Restart the service using the same command that was used to start the service.
Which one has better performance, swoole or java?
Apr 09, 2024 pm 07:03 PM
Performance comparison: Throughput: Swoole has higher throughput thanks to its coroutine mechanism. Latency: Swoole's coroutine context switching has lower overhead and smaller latency. Memory consumption: Swoole's coroutines occupy less memory. Ease of use: Swoole provides an easier-to-use concurrent programming API.
Swoole in action: How to use coroutines for concurrent task processing
Nov 07, 2023 pm 02:55 PM
Swoole in action: How to use coroutines for concurrent task processing Introduction In daily development, we often encounter situations where we need to handle multiple tasks at the same time. The traditional processing method is to use multi-threads or multi-processes to achieve concurrent processing, but this method has certain problems in performance and resource consumption. As a scripting language, PHP usually cannot directly use multi-threading or multi-process methods to handle tasks. However, with the help of the Swoole coroutine library, we can use coroutines to achieve high-performance concurrent task processing. This article will introduce
How is the swoole coroutine scheduled?
Apr 09, 2024 pm 07:06 PM
Swoole coroutine is a lightweight concurrency library that allows developers to write concurrent programs. The Swoole coroutine scheduling mechanism is based on the coroutine mode and event loop, using the coroutine stack to manage coroutine execution, and suspend them after the coroutine gives up control. The event loop handles IO and timer events. When the coroutine gives up control, it is suspended and returns to the event loop. When an event occurs, Swoole switches from the event loop to the pending coroutine, completing the switch by saving and loading the coroutine state. Coroutine scheduling uses a priority mechanism and supports suspend, sleep, and resume operations to flexibly control coroutine execution.
