Application practice of efficient message communication processing based on Swoole

In recent years, with the rapid development of the Internet, people's demand for real-time communication and high concurrency has become higher and higher. Faced with such a demand, developers must seek an efficient, fast, stable and easy-to-maintain solution. Swoole, a fully asynchronous, high-performance network communication framework based on the PHP language, is an option worth trying.

Swoole is a high-performance asynchronous concurrency framework that can use the PHP language and is different from the traditional AyncIO solution. It elevates process processing capabilities to a new level. Swoole can not only perform asynchronous MySQL query, asynchronous Redis, and asynchronous HTTP/WebSocket processing, but can also be installed into the PHP language running environment, providing intuitive support for TCP/UDP/Unix Socket, maximizing developers' programming efficiency.

For communication scenarios, Swoole's performance has been greatly improved compared to the traditional PHP concurrency framework. The specific performance is as follows:

1. Coroutine and asynchronous: Swoole's fast concurrent processing performance benefits from its coroutine-based and asynchronous implementation. In high-concurrency scenarios such as flash sales and red envelope grabbing, it can quickly and elegantly solve problems caused by short-term and large-scale congestion of client requests.

2. High performance: Because Swoole uses pure C or C as the core, it has excellent performance. In high-concurrency scenarios, its TCP/UDP server has excellent processing performance, expansion, and fault tolerance. A significant improvement.

3. Multi-process: Through Swoole's multi-process support, client requests can be processed quickly and efficiently, improving the response speed of the server.

4. Memory management: Swoole provides users with convenient memory management tools such as memory pools and buffers to avoid excessive memory allocation and recycling, thereby improving service efficiency.

In addition to these advantages, Swoole also has many advanced features, such as using Reactor for asynchronous network IO processing, using EventLoop to execute IO drivers, etc. Now, let's take a look at how Swoole can help us solve the problem of high concurrent communication through a practical application scenario.

1. Application scenario:

A client application of a certain company has a specific requirement - it needs to obtain real-time stock quotation data from the server quickly and efficiently. As the company's business continues to develop, the existing PHP synchronization MySQL query solution is unable to cope with such high-density concurrency tasks. In order to solve this problem, the company's technical department decided to use Swoole, a new fully asynchronous, high-performance network communication framework.

2. Solution:

1. Server

The company first used Swoole to build a high-performance TCP server to provide stock data responses requested by the client. Serve. The server uses asynchronous MySQL to query stock quotation data. After the data query is returned, it is packaged into JSON format data, and the data is sent back to the client through the server socket Socket. Among them, Swoole, as the TCP server, is responsible for receiving and processing the client's data requests, and packaging the return results into JSON data and sending it back to the client. In this way, the server can respond quickly and support requests in high-concurrency scenarios.

Due to Swoole's asynchronous MySQL query solution, the server reduces the time overhead of waiting for PHP to open the MySQL connection, query MySQL, and close the MySQL connection, improving response speed and concurrent processing capabilities.

2. Client

For client applications, use the asynchronous client class provided by Swoole to realize the client sending data requests to the server and receiving the server's response. The update frequency of the real-time stock price data displayed on the client is greatly increased. At the same time, the client's request to the server becomes faster and the response is more real-time. There is no problem of client application crash caused by massive congestion.

3. Summary

Through an actual application scenario practice, we demonstrated the use of Swoole, a fully asynchronous, high-performance, easy-to-maintain and expand network communication framework to build high-concurrency communication services. ability. After applying Swoole, enterprises can greatly improve the response speed and efficiency of the server, avoid business problems caused by massive congestion, and expand the processing scope of the service more flexibly.

Although Swoole is compatible with the PHP language, in order to give full play to its performance advantages, it needs to be developed for its features. Under the premise of following Swoole's asynchronous execution, you should try to avoid using too many synchronous blocking I/O calling codes so that the program can respond to client requests quickly and efficiently. Therefore, the code needs to be refactored and designed appropriately to achieve the best performance.
