Do you want to know the latest trends in the restaurant industry, but don't have the time or expertise to sort through Yelp data? This project takes care of the heavy lifting for you.

This project aims to learn and get hands-on experience working with different data engineering tools and technologies. So yes, there is space for improvement (A LOT!) but it's a very good start.

Cloud Composer starts the Airflow DAG that executes these tasks:

👉 Get the Yelp data

👉 Submit Spark jobs to Dataproc, which processes and ingests data into BigQuery

👉 Perform DBT transformations on top of it to answer business questionsAnd finally, these DBT models are used for visualization on Google Data Studio.

🎯 𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞𝐬:

👉 Cloud Composer single-handedly proved to be the most significant road blocker for this project. It seems it wasn't working as it should, in the asia-south1 region compared to the us-central1.

👉 Orchestrating DBT core jobs through Cloud Composer was another challenge. But I got a workaround using Cloud Run for that.
