Look inside

Step into the role of a data engineer working at an enterprise. Your task is to build a data lake’s serving layer and ensure that business queries run on it in a matter of seconds. You’ll start with reading cleansed data that’s already sitting in the curated layer. Then you’ll transform it, enrich it, aggregate it, and denormalize it using Apache Spark. When you’re finished, you’ll have multiple output tables that make up the serving layer of the data lake.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
