Jobukyu

A flexible, REST-based job queue.

Features

• Create, modify, and remove jobs via a REST API
• Store arbitrary data in the job
• Transmit data on job updates via Web Hooks
• Quick start using jobukyu's command line interface

Why Jobukyu?

At Axisto Media, we had a requirement to run a processor-intensive task (generating images of slides from a PDF file) on a server separate to those running the web application.

We originally tried Kue, but encountered issues using it, and so decided to create a tool that handled failing jobs gracefully.

In order to cater for the different kind of processor-intensive jobs we handle at Axisto, we created a tool that did not require implicit knowledge of our web application - it simply provided a REST API that the web application could interact with, store any kind of JSON data that we needed the job worker to know, and a way for the Job Queue to communicate the state of those jobs back to the web application.

Dependencies

Usage

The Job Queue is accessed via a REST API. There is a single resource called job.

REST API

GET     /jobs                 Lists all of the jobs in the queue, regardless of status
POST    /jobs                 Creates a job
GET     /jobs/new             Lists all of the jobs that are yet to be processed
GET     /jobs/processing      Lists all of the jobs that are being processed
GET     /jobs/completed       Lists all of the jobs that have completed
GET     /jobs/failed          Lists all of the jobs that failed
GET     /jobs/search          Search for jobs based on search criteria
GET     /jobs/:id             Shows a job's details
PUT     /jobs/:id             Updates a job
PUT     /jobs/:id/take        Marks a job's status as 'processing', so that no other workers can take it
PUT     /jobs/:id/release     Marks a job's status as 'new', so that other workers can take it
PUT     /jobs/:id/complete    Marks a job's status as 'completed'
PUT     /jobs/:id/fail        Marks a job's status as 'failed'
PUT     /jobs/:id/retry       Marks a job's status from 'failed' to 'new'
DELETE  /jobs/:id             Deletes a job from the queue
