Goblero

Pure Go, Simple, Embedded, Persistent Job Queue, backed by BadgerDB

DO NOT USE IN PRODUCTION This library is still in Alpha / Work In Progress

About Goblero

Intro article: Introducing Goblero: a Go Embedded Job Queue

Pure Go library, no cgo
Simple, embedded, persistent job queue
Provides in-process job processing to any Go app
The jobs/status changes are persisted to disk after each operation and pending jobs can continue processing after an app restart or a crash
Allows multiple "processors", each processor/worker processes one job at a time then is assigned a new job, etc
The storage engine used is BadgerDB

P.S: Why is the library named Goblero ? Go for the Go programming language obviously, and Badger in french is "Blaireau", but blero is easier to pronounce :)

Usage

The full API is documented on godoc.org. There is also a demo repo goblero-demo

Get package

go get -u github.com/didil/goblero/pkg/blero

API

// Create a new Blero backend
bl := blero.New("db/")

// Start Blero
bl.Start()

// defer Stopping Blero
defer bl.Stop()

// register a processor
bl.RegisterProcessorFunc(func(j *blero.Job) error {
  // Do some processing, access job name with j.Name, job data with j.Data
})

// enqueue a job
bl.EnqueueJob("MyJob", []byte("My Job Data"))
