Challenge Overview

Challenge Objectives

To create a processor that calculates the score of a submission based on the elapsed time

Project Background

Technology Stack

Code access

This is the first contest and thus there is no existing source code. You will be writing the app from scratch. However, you will find that the code base and functionality is very similar to the existing submission scoring processor code. You can certainly use this as reference and write a new aggregate score processor.

Individual requirements

Create a Kafka Listener (Major Requirement)

Create a nodejs based Kafka listener that will listen to multiple topics on Kafka.
The topics of concern are related to the event where a submission is created or updated, for the “review” resource
Use no-kafka module

Create an Aggregate Score Processor

After receiving the message from kafka, you will proceed to filter out relevant messages and proceed to determine an “aggregate score”. The details of this are shared in the contest forum.

Create Unit Tests (Minor Requirement)

Deployment guide and validation document

Provide a README.md that contains instructions on how to config, build, deploy the app locally
You are not required to deploy to heroku. However, you need to ensure that your submission can be deployed without any changes to heroku.

Important Notes

Use async and await pattern in your code base. Please don’t use yields and generators. Use promises.
Lint your code base using the standard module.
Note that you will be using Nodejs version 10 for this project.
��Both the kafka listener and the processor are part of the same code base. The processor is just a service that makes use of the kafka listener. See the reference code base for implementation details.

Zip your code base and upload it to Topcoder.
