Most programming in Go makes great use of typical design patterns-common to most languages-along with concurrency and other idiomatic patterns that play to Go’s strengths. These patterns have all used Go’s concurrency primitives: goroutines, channels, and select statements, primarily to focus on readable, maintainable code.

Worker Pool Pattern

Used to limit the number of concurrent tasks being executed, improving resource utilization and system stability.

package main
import (
 "fmt"
 "sync"
 "time"
)
func worker(id int, jobs <-chan int, results chan<- int) {
 for j := range jobs {
  fmt.Printf("Worker %d processing job %d\n", id, j)
  time.Sleep(time.Second) // Simulate work
  results <- j * 2        // Return result
 }
}
func main() {
 const numWorkers = 3
 const numJobs = 5
 jobs := make(chan int, numJobs)
 results := make(chan int, numJobs)
 // Start worker goroutines
 for w := 1; w <= numWorkers; w++ {
  go worker(w, jobs, results)
 }
 // Send jobs to the channel
 for j := 1; j <= numJobs; j++ {
  jobs <- j
 }
 close(jobs)…
