The best practices for Golang function concurrency control in microservice architecture include: using WaitGroup to coordinate concurrent routines to ensure that the main routine continues execution after all routines have been executed. Use Semaphores to control the concurrency limit and prevent system overload. Use Mutex to serialize access to shared resources and prevent data races. Use Goroutines channels to implement asynchronous communication between goroutines and decouple routines to improve concurrency.
The best practice of Golang function concurrency control in microservice architecture
In microservice architecture, function concurrency control is important for Optimizing performance and scalability is critical. Golang provides several mechanisms to effectively control function concurrency.
Best Practices:
import ( "sync" "time" ) var wg sync.WaitGroup func main() { for i := 0; i < 10; i++ { wg.Add(1) go func() { time.Sleep(time.Second) wg.Done() }() } wg.Wait() }
import ( "fmt" "sync" ) var sem = make(chan int, 10) func main() { for i := 0; i < 20; i++ { go func(i int) { sem <- 1 fmt.Printf("Routine %d started\n", i) time.Sleep(time.Second) <-sem }(i) } }
import ( "fmt" "sync" ) var m = sync.Mutex{} var counter = 0 func main() { for i := 0; i < 1000; i++ { go func() { m.Lock() counter++ fmt.Printf("Counter: %d\n", counter) m.Unlock() }() } }
import ( "fmt" ) func main() { ch := make(chan int) go func() { ch <- 10 }() v := <-ch fmt.Printf("Received: %d\n", v) }
Practical case:
The following is a practical example of using WaitGroup to coordinate concurrent routines:
package main import ( "fmt" "sync" "time" ) func main() { var wg sync.WaitGroup for i := 0; i < 10; i++ { wg.Add(1) go func(i int) { defer wg.Done() fmt.Println(i) time.Sleep(time.Second) }(i) } wg.Wait() }
