Bee Queue - A simple, fast, robust job/task queue for Node.js, backed by Redis

•    Javascript

---

A simple, fast, robust job/task queue for Node.js, backed by Redis.Bee-Queue is meant to power a distributed worker pool and was built with short, real-time jobs in mind. A web server can enqueue a job, wait for a worker process to complete it, and return its results within an HTTP request. Scaling is as simple as running more workers.

evQueue - Job scheduler and queueing engine

•    C++

---

evQueue is an open source job scheduler and queueing engine. It features an event-driven C++ engine and a PHP / MySQL web control interface which provides tasks monitoring and creation. It provides both simple task execution and complex task chaining (workflow) using an easy to use drag & drop web interface. Workflow description includes output linking to input, conditions, loops... Queues management provides an easy way for task parallelization and resource control.

Celery - Distributed Task Queue

•    Python

---

Celery is an asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well. The execution units, called tasks, are executed concurrently on a single or more worker servers using multiprocessing, Eventlet, or gevent. Tasks can execute asynchronously (in the background) or synchronously (wait until ready).

Faktory - "Takin' care of business, workin' overtime"

•    Go

---

At a high level, Faktory is a work server. It is the repository for background jobs within your application. Jobs have a type and a set of arguments and are placed into queues for workers to fetch and execute.You can use this server to distribute jobs to one or hundreds of machines. Jobs can be executed with any language by clients using the Faktory API to fetch a job from a queue.

react-native-queue - A React Native Job Queue

•    Javascript

---

A React Native at-least-once priority job queue / task queue backed by persistent Realm storage. Jobs will persist until completed, even if user closes and re-opens app. React Native Queue is easily integrated into OS background processes (services) so you can ensure the queue will continue to process until all jobs are completed even if app isn't in focus. It also plays well with Workers so your jobs can be thrown on the queue, then processed in dedicated worker threads for greatly improved processing performance. React Native Queue is designed to be a swiss army knife for task management in React Native. It abstracts away the many annoyances related to processing complex tasks, like durability, retry-on-failure, timeouts, chaining processes, and more. Just throw your jobs onto the queue and relax - they're covered.

Fireworq - Lightweight, high-performance, language-independent job queue system

•    Go

---

Fireworq is a lightweight, high-performance job queue system with the following abilities. It is available from ANY programming language which can talk HTTP. It works with a single binary without external dependencies. It is built on top of RDBMS (MySQL), so that jobs won't be lost even if the job queue process dies. You can apply an ordinary replication scheme to the underlying DB for the reliability of the DB itself.

Resque - Job queue in Ruby

•    Ruby

---

Resque is a Redis-backed Ruby library for creating background jobs, placing them on multiple queues, and processing them later. Queues are picked off in order of their priority. A job from a lower priority queue will only be picked off if there are no jobs for a higher priority queue available.

huey - a little task queue for python

•    Python

---

huey is a little task queue in Python. It supports multi-process, multi-thread or greenlet task execution models. It can schedule tasks to execute at a given time, or after a given delay, schedule recurring tasks, like a crontab, retry tasks that fail automatically, task result storage.

Quartz - A full-featured, Java-based, In-process job scheduler

•    Java

---

Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side virtually any Java EE or Java SE application - from the smallest stand-alone application to the largest e-commerce system.

OBAN - Robust job processing in Elixir, backed by modern PostgreSQL

•    Elixir

---

Oban's primary goals are reliability, consistency and observability. It is fundamentally different from other background job processing tools because it retains job data for historic metrics and inspection. You can leave your application running indefinitely without worrying about jobs being lost or orphaned due to crashes.

Bistro - Flexible distributed scheduler, a high-performance framework supporting multiple paradigms while retaining ease of configuration, management, and monitoring

•    C++

---

Bistro is a toolkit for making services that schedule and execute tasks. Bistro is a toolkit for making distributed computation systems. It can schedule and run distributed tasks, including data-parallel jobs. It enforces resource constraints for worker hosts and data-access bottlenecks. It supports remote worker pools, low-latency batch scheduling, dynamic shards, and a variety of other possibilities. It has command-line and web UIs.

chronos - Fault tolerant job scheduler for Mesos which handles dependencies and ISO8601 based schedules

•    Scala

---

Chronos is a replacement for cron. It is a distributed and fault-tolerant scheduler that runs on top of Apache Mesos that can be used for job orchestration. It supports custom Mesos executors as well as the default command executor. Thus by default, Chronos executes sh (on most systems bash) scripts. Chronos can be used to interact with systems such as Hadoop (incl. EMR), even if the Mesos agents on which execution happens do not have Hadoop installed. Included wrapper scripts allow transfering files and executing them on a remote machine in the background and using asynchronous callbacks to notify Chronos of job completion or failures. Chronos is also natively able to schedule jobs that run inside Docker containers.

Sidekiq - Simple, efficient background processing for Ruby

•    Ruby

---

Simple, efficient background processing for Ruby. Sidekiq uses threads to handle many jobs at the same time in the same process. It does not require Rails but will integrate tightly with Rails 3/4 to make background processing dead simple. Sidekiq uses multithreading so it is much more memory efficient than Resque (which forks a new process for every job).

workq - Job server in Go

•    Go

---

Workq is a job scheduling server strictly focused on simplifying job processing and streamlining coordination. It can run jobs in blocking foreground or non-blocking background mode. Workq runs as a standalone TCP server and implements a simple, text based protocol. Clients interact with Workq over a TCP socket in a request/response model with text commands. Please refer to the full protocol doc for details.
