goworker
goworker is a Go-based background worker that runs 10 to 100,000* times faster than Ruby-based workers. -

go-workers
DISCONTINUED. ๐ท Library for safely running groups of workers concurrently or consecutively that require input and output through channels -
async
A safe way to execute functions asynchronously, recovering them in case of panic. It also provides an error stack aiming to facilitate fail causes discovery. -

-
gollback
Go asynchronous simple function utilities, for managing execution of closures and callbacks -
-

-
gpool
gpool - a generic context-aware resizable goroutines pool to bound concurrency based on semaphore. -
-
-
gowl
Gowl is a process management and process monitoring tool at once. An infinite worker pool gives you the ability to control the pool and processes and monitor their status. -
routine
go routine control, abstraction of the Main and some useful Executors.ๅฆๆไฝ ไธไผ็ฎก็Goroutine็่ฏ๏ผ็จๅฎ -

kyoo
Unlimited job queue for go, using a pool of concurrent workers processing the job queue entries -

-
execpool
A pool that spins up a given number of processes in advance and attaches stdin and stdout when needed. Very similar to FastCGI but works for any command. -

-
concurrency-limiter
Concurrency limiter with support for timeouts , dynamic priority and context cancellation of goroutines. -
conexec
A concurrent toolkit to help execute funcs concurrently in an efficient and safe way. It supports specifying the overall timeout to avoid blocking. -
-
queue
package queue gives you a queue group accessibility. Helps you to limit goroutines, wait for the end of the all goroutines and much more. -
hands
Hands is a process controller used to control the execution and return strategies of multiple goroutines. -
async-job
AsyncJob is an asynchronous queue job manager with light code, clear and speed. I hope so ! ๐ฌ -

README
Hunch
Hunch provides functions like: All, First, Retry, Waterfall etc., that makes asynchronous flow control more intuitive.
About Hunch
Go have several concurrency patterns, here're some articles:
- https://blog.golang.org/pipelines
- https://blog.golang.org/context
- https://blog.golang.org/go-concurrency-patterns-timing-out-and
- https://blog.golang.org/advanced-go-concurrency-patterns
But nowadays, using the context package is the most powerful pattern.
So base on context, Hunch provides functions that can help you deal with complex asynchronous logics with ease.
Usage
Installation
go get
$ go get -u -v github.com/aaronjan/hunch
go mod (Recommended)
import "github.com/aaronjan/hunch"
$ go mod tidy
Types
type Executable func(context.Context) (interface{}, error)
type ExecutableInSequence func(context.Context, interface{}) (interface{}, error)
API
All
func All(parentCtx context.Context, execs ...Executable) ([]interface{}, error)
All returns all the outputs from all Executables, order guaranteed.
Examples
ctx := context.Background()
r, err := hunch.All(
ctx,
func(ctx context.Context) (interface{}, error) {
time.Sleep(300 * time.Millisecond)
return 1, nil
},
func(ctx context.Context) (interface{}, error) {
time.Sleep(200 * time.Millisecond)
return 2, nil
},
func(ctx context.Context) (interface{}, error) {
time.Sleep(100 * time.Millisecond)
return 3, nil
},
)
fmt.Println(r, err)
// Output:
// [1 2 3] <nil>
Take
func Take(parentCtx context.Context, num int, execs ...Executable) ([]interface{}, error)
Take returns the first num values outputted by the Executables.
Examples
ctx := context.Background()
r, err := hunch.Take(
ctx,
// Only need the first 2 values.
2,
func(ctx context.Context) (interface{}, error) {
time.Sleep(300 * time.Millisecond)
return 1, nil
},
func(ctx context.Context) (interface{}, error) {
time.Sleep(200 * time.Millisecond)
return 2, nil
},
func(ctx context.Context) (interface{}, error) {
time.Sleep(100 * time.Millisecond)
return 3, nil
},
)
fmt.Println(r, err)
// Output:
// [3 2] <nil>
Last
func Last(parentCtx context.Context, num int, execs ...Executable) ([]interface{}, error)
Last returns the last num values outputted by the Executables.
Examples
ctx := context.Background()
r, err := hunch.Last(
ctx,
// Only need the last 2 values.
2,
func(ctx context.Context) (interface{}, error) {
time.Sleep(300 * time.Millisecond)
return 1, nil
},
func(ctx context.Context) (interface{}, error) {
time.Sleep(200 * time.Millisecond)
return 2, nil
},
func(ctx context.Context) (interface{}, error) {
time.Sleep(100 * time.Millisecond)
return 3, nil
},
)
fmt.Println(r, err)
// Output:
// [2 1] <nil>
Waterfall
func Waterfall(parentCtx context.Context, execs ...ExecutableInSequence) (interface{}, error)
Waterfall runs ExecutableInSequences one by one, passing previous result to next Executable as input. When an error occurred, it stop the process then returns the error. When the parent Context canceled, it returns the Err() of it immediately.
Examples
ctx := context.Background()
r, err := hunch.Waterfall(
ctx,
func(ctx context.Context, n interface{}) (interface{}, error) {
return 1, nil
},
func(ctx context.Context, n interface{}) (interface{}, error) {
return n.(int) + 1, nil
},
func(ctx context.Context, n interface{}) (interface{}, error) {
return n.(int) + 1, nil
},
)
fmt.Println(r, err)
// Output:
// 3 <nil>
Retry
func Retry(parentCtx context.Context, retries int, fn Executable) (interface{}, error)
Retry attempts to get a value from an Executable instead of an Error. It will keeps re-running the Executable when failed no more than retries times. Also, when the parent Context canceled, it returns the Err() of it immediately.
Examples
count := 0
getStuffFromAPI := func() (int, error) {
if count == 5 {
return 1, nil
}
count++
return 0, fmt.Errorf("timeout")
}
ctx := context.Background()
r, err := hunch.Retry(
ctx,
10,
func(ctx context.Context) (interface{}, error) {
rs, err := getStuffFromAPI()
return rs, err
},
)
fmt.Println(r, err, count)
// Output:
// 1 <nil> 5
