What is Recruiter

Recruiter is a Job Queue Manager built with PHP meant to be used in PHP projects.

It allow php developers to perform some operations in background.

Features and characteristics:

• Jobs are made persistent on MongoDB
• Jobs with complex and customizable strategies
• Jobs are stored by default in an history collection for after the fact inspection and analytics
• Multiple queues are supported through grouping
• Built to be robust, scalable and fault tolerant

At high level, it provides a few major components:

• A recruiter: a single instance long-running process who assign enqueued jobs to a worker
• A worker: a multiple instace long-running processes that each execute a single job at a time
• A cleaner: a single instance long-running process who takes care of cleaning up the dirty conditions that can happen (i.e. worker dead for a fatal error)

Why

DA COMPLETARE

Onebip is a payment system (think PayPal with mobile devices in place of credit cards), things like: payment notifications, subscription renewals, remainder messages, … are really important. You cannot skip or lose a job (notification are idempotent but payments are not). You cannot forgot to have completed a job (customer/merchant support must have data to do their job). You need to know if and when you can retry a failed job (external services have rate limits and are based on agreements/contracts). We have developed internally our job/queue solution called Recruiter. After a year in production and many billions of jobs we have decided to put what we have learned into a stand alone project and to make it available to everyone.
