v0.1.0

Release Notes for v0.1.0

Initial release of go-pooler.

Overview

go-pooler is a simple and generic resource pooler for managing reusable resources in Go. It is designed to handle resource acquisition, release, and health checks efficiently, making it suitable for high-concurrency applications.

Features

• Acquiring and Releasing Resources by Key: Manage resources using unique keys.
• Configurable Maximum Number of Open Resources: Limit the number of open resources.
• Periodic Health Checks: Automatically perform health checks and resource cleanup at configurable intervals.
• Pool Statistics: Gather statistics about the pool's usage, such as the number of open resources and wait times.

Installation

To install the package, use:

go get github.com/bartventer/go-pooler

Basic Usage

To create a new pool, define a resource that implements the Reusable interface and use the NewPool function:

package main

import (
	"context"

	"github.com/bartventer/go-pooler"
)

type Worker struct{}
type WorkerPool = pooler.Pool[*Worker]

func (w *Worker) Close() error                          { return nil }
func (w *Worker) PingContext(ctx context.Context) error { return nil }

func WorkerFactory() (*Worker, error) {
	return &Worker{}, nil
}

func NewWorkerPool(ctx context.Context, opts ...pooler.Option) *WorkerPool {
	return pooler.NewPool(ctx, WorkerFactory, opts...)
}

func main() {
	ctx := context.Background()
	p := NewWorkerPool(ctx, pooler.WithMaxOpenResources(1))

	_, err := p.Acquire(ctx, "key1")
	if err != nil {
		panic(err)
	}
	defer p.Release("key1")

	// Use the worker...
}
