golang High concurrency processing

In the Go framework architecture, the key strategies to improve high concurrency processing capabilities are: using the lightweight concurrency mechanism of Goroutine to execute tasks in parallel and improve CPU utilization. Use concurrent channels for safe and efficient data exchange between coroutines to ensure data consistency and concurrency. Implement an asynchronous processing mechanism to move time-consuming tasks to the background for execution to avoid blocking request responses and improve response capabilities.

High concurrency processing in Go framework architecture

In modern distributed systems, high concurrency processing capabilities are crucial. This requires an architectural design that can efficiently handle large numbers of concurrent requests. As an efficient and concurrent programming language, Go provides a solid foundation for building highly concurrent applications. This article will explore the best practices for achieving high concurrency processing in the Go framework architecture.

Coroutine concurrency

Go's Goroutine is a lightweight thread that provides a non-blocking concurrency mechanism. Coroutines can be executed in parallel in a logical execution flow, effectively utilizing multi-core CPU resources. The framework can manage the life cycle of coroutines by creating a coroutine pool to ensure efficient concurrent request processing.

Case: Gin Framework

Gin is a popular Go HTTP framework that uses a coroutine-based concurrency architecture. It uses a goroutine pool to handle requests, allowing multiple requests to be processed in parallel, resulting in faster response times.

package main

import (
    "github.com/gin-gonic/gin"
)

func main() {
    r := gin.Default()
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })
    r.Run() // listen and serve on 0.0.0.0:8080
}

Concurrent channel

Concurrent channel is a communication mechanism used to safely transfer data between coroutines. Go provides several built-in channels for concurrent communication, such as chan. The framework can use channels to coordinate tasks and data exchanges between coroutines to ensure data security and concurrency.

Case: Echo Framework

Echo is another popular Go HTTP framework that uses concurrent channels to manage asynchronous tasks. By placing tasks into a channel, Echo can process requests in parallel and ensure sequential execution of tasks.

package main

import (
    "github.com/labstack/echo/v4"
    "time"
)

func main() {
    e := echo.New()
    e.GET("/ping", func(c echo.Context) error {
        time.Sleep(100 * time.Millisecond) // 模拟一个耗时任务
        return c.JSON(200, map[string]interface{}{
            "message": "pong",
        })
    })
    e.Start(":8080")
}
Copy after login

Asynchronous processing

Asynchronous processing can perform time-consuming tasks in the background without blocking the request response. Go provides WaitGroup and other mechanisms that can be used to synchronize and wait for multiple asynchronous tasks to complete. Frameworks can improve responsiveness by implementing asynchronous processing and avoid request delays caused by long-term blocking tasks.

Case: Beego Framework

Beego is a Go Web framework suitable for large projects. It provides a built-in asynchronous task processing mechanism, allowing developers to create asynchronous tasks and specify their processing functions.

package main

import (
    "github.com/astaxie/beego"
)

type Task struct {
    Name string
}

func main() {
    beego.Router("/", &mainController{})
    asyncQueue := beego.NewAsync()
    asyncQueue.Push(Task{Name: "task1"})
    beego.Run()
}

type mainController struct {
    beego.Controller
}
Copy after login

Conclusion

By using technologies such as coroutine concurrency, concurrent channels, and asynchronous processing, the Go framework can achieve efficient high-concurrency processing. These best practices enable applications to take full advantage of modern multi-core processors to provide responsive and scalable network services.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Golang framework vs. Go framework: Comparison of internal architecture and external features Golang framework vs. Go framework: Comparison of internal architecture and external features Jun 06, 2024 pm 12:37 PM

The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.
