Background Job System

https://www.codementor.io/projects/background-job-system-atx32exogo

I have three separate apps,

• backgroundjob-backend - receive fake job as and add the queue as requestful api, built using Java 15, spring boot, reactive spring, h2 database
• backgroundjob-ui - react UI to add jobs and display list, built using reactjs redux
• fakeServer - fake server to receive a callback when a job is executed, built using spring boot

Prerequisites:

• Java 15
• node 15
• gradle (the latest one)
• npm

Clone all three repo:

git clone --recursive https://github.com/rokon12/background-job-system.git
cd background-job-system

Start the backend server:

cd backgroundjob-backend
./gradlew bootRun

Start the UI:

cd backgroundjob-ui
npm start

Start FakeServer

cd fakeServer
./gradlew bootRun

The above fake server is not required to run, but if you run, you will get a callback with job status.

The backgroundjob-backend will create 100 fake jobs and will keep running. There is a corn job that runs every minutes and pull 10 jobs from the database that are not completed. A job can be in one of these four statuses.

• QUEUED
• STARTED
• FAILED
• COMPLETED

What do you mean with 'job'?

A job is composed by following fields.

• a job name
• a payload, could be anything, since its all fake
• a callback url, once job is executed, this url will be called

How add a new job to the Queue
