Introduction

How does rethinkdb-job-queue work?

The main component of rethinkdb-job-queue is the Queue object.

Throughout this documentation you will see references to either the "Queue object" or the "queue". So what do these terms mean?

• "Queue object" is referencing the local JavaScript object created by calling const q = new Queue().
• "queue" is referencing the list of jobs that need to be processed either by a local Queue object or by another Node.js process Queue object.

As you can see above, it is easy to create a Queue object. Here is a slightly more complete example.

const Queue = require('rethinkdb-job-queue')
const q = new Queue({ name: 'EmailJobs' })

You will notice in the example above that the name of the queue is being set to 'EmailJobs' by changing the Queue-Options. If this is the first time you have created a Queue object called 'EmailJobs' then the following will take place as part of the instantiation of the Queue object.

• Does the database exist? If not create it.
• Does the table in the database exist? If not create it.
