Idiomatic Code Recipes & Concurrency Patterns
package main

"sync"
)
// ProcessJobs executes tasks concurrently with bounded worker pools
func ProcessJobs(ctx context.Context, concurrency int, jobs []int) {
ch := make(chan int, concurrency)
var wg sync.WaitGroup
for i := 0; i < concurrency; i++ {
wg.Add(1)
go func(workerId int) {
defer wg.Done()
for job := range ch {
fmt.Printf("[Worker #%d] Executing Task #%d
", workerId, job)
}
}(i)
}
for _, j := range jobs {
ch <- j
}
close(ch)
wg.Wait()
