In this article, let us look at the Medallion Architecture — a data design pattern that organises your data lake into three layers: Bronze, Silver, and Gold. If you have heard terms like “bronze ta...
When I started building data pipelines on Databricks, the orchestration piece was always the awkward part. You would write your notebooks, get the transformations working, and then you had to figur...
When I first started working with GCP, I kept hearing about Dataflow but wasn’t quite sure where it fit. We had Cloud Functions for light event-driven work, Composer (managed Airflow) for orchestra...
If you have worked with BigQuery for any reasonable amount of time, you have probably stared at a query that scanned a few hundred gigabytes when it really only needed a few megabytes. That is usua...

In this article let us look at how you can use GitHub Actions to set up a simple CI/CD pipeline for your data workflows. If you are building dbt models, Airflow DAGs, or Python-based ETL scripts an...
In this article, we will build a simple but real ETL pipeline using Apache Airflow. If you have been writing cron jobs or one-off scripts to move data around and are looking for something more mana...
If you have spent any time in the data engineering space over the last couple of years, you have probably heard about table formats — Delta Lake, Apache Iceberg, Apache Hudi. They all sound like th...
