grpool
Lightweight Goroutine pool
Clients can submit jobs. Dispatcher takes job, and sends it to first available worker. When worker is done with processing job, will be returned back to worker pool.
Number of workers and Job queue size is configurable.

Simple example
package main
import (
"fmt"
"runtime"
"time"
"github.com/ivpusic/grpool"
)
func main() {
// number of workers, and size of job queue
pool := grpool.NewPool(100, 50)
// release resources used by pool
defer pool.Release()
// submit one or more jobs to pool
for i := 0; i < 10; i++ {
count := i
pool.JobQueue <- func() {
fmt.Printf("I am worker! Number %d\n", count)
}
}
// dummy wait until jobs are finished
time.Sleep(1 * time.Second)
}Example with waiting jobs to finish
package main
import (
"fmt"
"runtime"
"github.com/ivpusic/grpool"
)
func main() {
// number of workers, and size of job queue
pool := grpool.NewPool(100, 50)
defer pool.Release()
// how many jobs we should wait
pool.WaitCount(10)
// submit one or more jobs to pool
for i := 0; i < 10; i++ {
count := i
pool.JobQueue <- func() {
// say that job is done, so we can know how many jobs are finished
defer pool.JobDone()
fmt.Printf("hello %d\n", count)
}
}
// wait until we call JobDone for all jobs
pool.WaitAll()
