# pond
|
||||||
|
Minimalistic and High-performance goroutine worker pool written in Go
|
||||||
|
|
||||||
|
## Motivation
|
||||||
|
|
||||||
|
This library is meant to provide a simple way to limit concurrency when executing some function over a limited resource or service.
|
||||||
|
|
||||||
|
Some common scenarios include:
|
||||||
|
|
||||||
|
- Executing queries against a Database with a limited no. of connections
|
||||||
|
- Sending HTTP requests to a a rate/concurrency limited API
|
||||||
|
|
||||||
|
## Features:
|
||||||
|
|
||||||
|
- Zero dependencies
|
||||||
|
- Create pools with fixed or dynamic size
|
||||||
|
- Worker goroutines are only created when needed (backpressure detection) and automatically purged after being idle for some time (configurable)
|
||||||
|
- Minimalistic APIs for:
|
||||||
|
- Creating worker pools with fixed or dynamic size
|
||||||
|
- Submitting tasks to a pool in a fire-and-forget fashion
|
||||||
|
- Submitting tasks to a pool and waiting for them to complete
|
||||||
|
- Submitting tasks to a pool with a deadline
|
||||||
|
- Submitting a group of tasks and waiting for them to complete
|
||||||
|
- Submitting a group of tasks associated to a Context
|
||||||
|
- Getting the number of running workers (goroutines)
|
||||||
|
- Stopping a worker pool
|
||||||
|
- Task panics are handled gracefully (configurable panic handler)
|
||||||
|
- Supports Non-blocking and Blocking task submission modes (buffered / unbuffered)
|
||||||
|
- Very high performance and efficient resource usage under heavy workloads, even outperforming unbounded goroutines in some scenarios (See [benchmarks](https://github.com/alitto/pond-benchmarks))
|
||||||
|
- Configurable pool resizing strategy, with 3 presets for common scenarios: Eager, Balanced and Lazy.
|
||||||
|
- Complete pool metrics such as number of running workers, tasks waiting in the queue [and more](#metrics--monitoring).
|
||||||
|
- **New (since v1.7.0)**: configurable parent context and graceful shutdown with deadline.
|
||||||
|
- [API reference](https://pkg.go.dev/github.com/alitto/pond)
|
||||||
|
|
||||||
|
## How to install
|
||||||
|
|
||||||
|
```bash
|
||||||
|
go get -u github.com/alitto/pond
|
||||||
|
```
|
||||||
|
|
||||||
|
## How to use
|
||||||
|
|
||||||
|
### Worker pool with dynamic size
|
||||||
|
|
||||||
|
``` go
|
||||||
|
package main
|
||||||
|
|
||||||
|
import (
|
||||||
|
"fmt"
|
||||||
|
|
||||||
|
"github.com/alitto/pond"
|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
|
||||||
|
// Create a buffered (non-blocking) pool that can scale up to 100 workers
|
||||||
|
// and has a buffer capacity of 1000 tasks
|
||||||
|
pool := pond.New(100, 1000)
|
||||||
|
|
||||||
|
// Submit 1000 tasks
|
||||||
|
for i := 0; i < 1000; i++ {
|
||||||
|
n := i
|
||||||
|
pool.Submit(func() {
|
||||||
|
fmt.Printf("Running task #%d\n", n)
|
||||||
|
})
|
||||||
|
}
|
||||||
|
|
||||||
|
// Stop the pool and wait for all submitted tasks to complete
|
||||||
|
pool.StopAndWait()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Worker pool with fixed size
|
||||||
|
|
||||||
|
``` go
|
||||||
|
package main
|
||||||
|
|
||||||
|
import (
|
||||||
|
"fmt"
|
||||||
|
|
||||||
|
"github.com/alitto/pond"
|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
|
||||||
|
// Create an unbuffered (blocking) pool with a fixed
|
||||||
|
// number of workers
|
||||||
|
pool := pond.New(10, 0, pond.MinWorkers(10))
|
||||||
|
|
||||||
|
// Submit 1000 tasks
|
||||||
|
for i := 0; i < 1000; i++ {
|
||||||
|
n := i
|
||||||
|
pool.Submit(func() {
|
||||||
|
fmt.Printf("Running task #%d\n", n)
|
||||||
|
})
|
||||||
|
}
|
||||||
|
|
||||||
|
// Stop the pool and wait for all submitted tasks to complete
|
||||||
|
pool.StopAndWait()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Submitting a group of tasks
|
||||||
|
|
||||||
|
``` go
|
||||||
|
package main
|
||||||
|
|
||||||
|
import (
|
||||||
|
"fmt"
|
||||||
|
|
||||||
|
"github.com/alitto/pond"
|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
|
||||||
|
// Create a pool
|
||||||
|
pool := pond.New(10, 1000)
|
||||||
|
defer pool.StopAndWait()
|
||||||
|
|
||||||
|
// Create a task group
|
||||||
|
group := pool.Group()
|
||||||
|
|
||||||
|
// Submit a group of tasks
|
||||||
|
for i := 0; i < 20; i++ {
|
||||||
|
n := i
|
||||||
|
group.Submit(func() {
|
||||||
|
fmt.Printf("Running group task #%d\n", n)
|
||||||
|
})
|
||||||
|
}
|
||||||
|
|
||||||
|
// Wait for all tasks in the group to complete
|
||||||
|
group.Wait()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Submitting a group of tasks associated to a context (**since v1.8.0**)
|
||||||
|
|
||||||
|
This feature provides synchronization, error propagation, and Context cancelation for subtasks of a common task. Similar to `errgroup.Group` from [`golang.org/x/sync/errgroup`](https://pkg.go.dev/golang.org/x/sync/errgroup) package with concurrency bounded by the worker pool.
|
||||||
|
|
||||||
|
``` go
|
||||||
|
package main
|
||||||
|
|
||||||
|
import (
|
||||||
|
"context"
|
||||||
|
"fmt"
|
||||||
|
"net/http"
|
||||||
|
|
||||||
|
"github.com/alitto/pond"
|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
|
||||||
|
// Create a worker pool
|
||||||
|
pool := pond.New(10, 1000)
|
||||||
|
defer pool.StopAndWait()
|
||||||
|
|
||||||
|
// Create a task group associated to a context
|
||||||
|
group, ctx := pool.GroupContext(context.Background())
|
||||||
|
|
||||||
|
var urls = []string{
|
||||||
|
"https://www.golang.org/",
|
||||||
|
"https://www.google.com/",
|
||||||
|
"https://www.github.com/",
|
||||||
|
}
|
||||||
|
|
||||||
|
// Submit tasks to fetch each URL
|
||||||
|
for _, url := range urls {
|
||||||
|
url := url
|
||||||
|
group.Submit(func() error {
|
||||||
|
req, err := http.NewRequestWithContext(ctx, http.MethodGet, url, nil)
|
||||||
|
resp, err := http.DefaultClient.Do(req)
|
||||||
|
if err == nil {
|
||||||
|
resp.Body.Close()
|
||||||
|
}
|
||||||
|
return err
|
||||||
|
})
|
||||||
|
}
|
||||||
|
|
||||||
|
// Wait for all HTTP requests to complete.
|
||||||
|
err := group.Wait()
|
||||||
|
if err != nil {
|
||||||
|
fmt.Printf("Failed to fetch URLs: %v", err)
|
||||||
|
} else {
|
||||||
|
fmt.Println("Successfully fetched all URLs")
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Pool Configuration Options
|
||||||
|
|
||||||
|
- **MinWorkers**: Specifies the minimum number of worker goroutines that must be running at any given time. These goroutines are started when the pool is created. The default value is 0. Example:
|
||||||
|
``` go
|
||||||
|
// This will create a pool with 5 running worker goroutines
|
||||||
|
pool := pond.New(10, 1000, pond.MinWorkers(5))
|
||||||
|
```
|
||||||
|
- **IdleTimeout**: Defines how long to wait before removing idle worker goroutines from the pool. The default value is 5 seconds. Example:
|
||||||
|
``` go
|
||||||
|
// This will create a pool that will remove workers 100ms after they become idle
|
||||||
|
pool := pond.New(10, 1000, pond.IdleTimeout(100 * time.Millisecond))
|
||||||
|
```
|
||||||
|
- **PanicHandler**: Allows to configure a custom function to handle panics thrown by tasks submitted to the pool. The default handler just writes a message to standard output using `fmt.Printf` with the following contents: `Worker exits from a panic: [panic] \n Stack trace: [stack trace]`). Example:
|
||||||
|
```go
|
||||||
|
// Custom panic handler function
|
||||||
|
panicHandler := func(p interface{}) {
|
||||||
|
fmt.Printf("Task panicked: %v", p)
|
||||||
|
}
|
||||||
|
|
||||||
|
// This will create a pool that will handle panics using a custom panic handler
|
||||||
|
pool := pond.New(10, 1000, pond.PanicHandler(panicHandler)))
|
||||||
|
```
|
||||||
|
- **Strategy**: Configures the strategy used to resize the pool when backpressure is detected. You can create a custom strategy by implementing the `pond.ResizingStrategy` interface or choose one of the 3 presets:
|
||||||
|
- **Eager**: maximizes responsiveness at the expense of higher resource usage, which can reduce throughput under certain conditions. This strategy is meant for worker pools that will operate at a small percentage of their capacity most of the time and may occasionally receive bursts of tasks. This is the default strategy.
|
||||||
|
- **Balanced**: tries to find a balance between responsiveness and throughput. It's suitable for general purpose worker pools or those that will operate close to 50% of their capacity most of the time.
|
||||||
|
- **Lazy**: maximizes throughput at the expense of responsiveness. This strategy is meant for worker pools that will operate close to their max. capacity most of the time.
|
||||||
|
``` go
|
||||||
|
// Example: create pools with different resizing strategies
|
||||||
|
eagerPool := pond.New(10, 1000, pond.Strategy(pond.Eager()))
|
||||||
|
balancedPool := pond.New(10, 1000, pond.Strategy(pond.Balanced()))
|
||||||
|
lazyPool := pond.New(10, 1000, pond.Strategy(pond.Lazy()))
|
||||||
|
```
|
||||||
|
- **Context**: Configures a parent context on this pool to stop all workers when it is cancelled. The default value `context.Background()`. Example:
|
||||||
|
``` go
|
||||||
|
// This creates a pool that is stopped when myCtx is cancelled
|
||||||
|
pool := pond.New(10, 1000, pond.Context(myCtx))
|
||||||
|
```
|
||||||
|
|
||||||
|
### Resizing strategies
|
||||||
|
|
||||||
|
The following chart illustrates the behaviour of the different pool resizing strategies as the number of submitted tasks increases. Each line represents the number of worker goroutines in the pool (pool size) and the x-axis reflects the number of submitted tasks (cumulative).
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
As the name suggests, the "Eager" strategy always spawns an extra worker when there are no idles, which causes the pool to grow almost linearly with the number of submitted tasks. On the other end, the "Lazy" strategy creates one worker every N submitted tasks, where N is the maximum number of available CPUs ([GOMAXPROCS](https://golang.org/pkg/runtime/#GOMAXPROCS)). The "Balanced" strategy represents a middle ground between the previous two because it creates a worker every N/2 submitted tasks.
|
||||||
|
|
||||||
|
### Stopping a pool
|
||||||
|
|
||||||
|
There are 3 methods available to stop a pool and release associated resources:
|
||||||
|
- `pool.Stop()`: stop accepting new tasks and signal all workers to stop processing new tasks. Tasks being processed by workers will continue until completion unless the process is terminated.
|
||||||
|
- `pool.StopAndWait()`: stop accepting new tasks and wait until all running and queued tasks have completed before returning.
|
||||||
|
- `pool.StopAndWaitFor(deadline time.Duration)`: similar to `StopAndWait` but with a deadline to prevent waiting indefinitely.
|
||||||
|
|
||||||
|
### Metrics & monitoring
|
||||||
|
|
||||||
|
Each worker pool instance exposes useful metrics that can be queried through the following methods:
|
||||||
|
|
||||||
|
- `pool.RunningWorkers() int`: Current number of running workers
|
||||||
|
- `pool.IdleWorkers() int`: Current number of idle workers
|
||||||
|
- `pool.MinWorkers() int`: Minimum number of worker goroutines
|
||||||
|
- `pool.MaxWorkers() int`: Maxmimum number of worker goroutines
|
||||||
|
- `pool.MaxCapacity() int`: Maximum number of tasks that can be waiting in the queue at any given time (queue capacity)
|
||||||
|
- `pool.SubmittedTasks() uint64`: Total number of tasks submitted since the pool was created
|
||||||
|
- `pool.WaitingTasks() uint64`: Current number of tasks in the queue that are waiting to be executed
|
||||||
|
- `pool.SuccessfulTasks() uint64`: Total number of tasks that have successfully completed their exection since the pool was created
|
||||||
|
- `pool.FailedTasks() uint64`: Total number of tasks that completed with panic since the pool was created
|
||||||
|
- `pool.CompletedTasks() uint64`: Total number of tasks that have completed their exection either successfully or with panic since the pool was created
|
||||||
|
|
||||||
|
In our [Prometheus example](./examples/prometheus/prometheus.go) we showcase how to configure collectors for these metrics and expose them to Prometheus.
|
||||||
|
