Scenario

A junior developer started working on a BI app for a company. The app will be used to visualize data from a PostgreSQL database, data raging in the order of millions of rows.

The data team defined the database schema to satisfy as best as possible the required data representation requirements.

The developer spent a few hours working on the app, achieving some progress, but then was assigned to another project.

Your task is to finish the work left undone and clean up the mess the junior developer left behind.

Main goals:

• All tests green
  • Starting from models/data_point_spec.rb
• The stubs in data_points/index are implemented

Side quests:

• Test the frontend with RSpec
• Implement filtering for all reasonable fields and relations
• Prepare the app for deployment in AWS ECS
