safeREACH code challenge

Welcome to our code challenge.

Notes

Some additional changes were performed.

• multistage dockerfile was created
• new make commands were created: build which will build application docker image and runall which will run both app and DB at the same time
• application was migrated to Java 11

Get started

0. Make sure you have a running Java and Docker set up (scripts written for Linux)
1. Start the database with make updb
2. Startup the SafeReachCodeChallengeApplication to initialize the database
3. Fill test data into the database with make init
4. Call http://localhost:8080/run in your browser
5. make run will call the test suite

About the challenge

You encountered a package in the java code named donottouch. Which includes the DoNotTouchProcessor. It does some strange calculations to process some Data. As a challenge participant it's your task to improve the execution speed our RunController and optimize the SafeReachCodeChallengeApplication.

Rules

• Do not touch the code inside the donottouch package or script/ folder.
• Everything else is allowed - be creative

Goal

• Process as much data in 10 seconds as possible
• Detect possible bottlenecks, showcase and solve them
• Push your code to GitHub repository
• Imagine multiple people work in this code case (issues, pull requests and commit messages matter)

We will take a look at the GitHub repo together and go over the code changes. Afterwards I will clone the repo, start the application and execute make run.

Bonus Goals (if your are "done" in under 2 hours or have some time left)

• Setup a CI Github actions workflow for this application
• Let GitHub actions create a docker image which is pushed to the GitHub package registry
