ETL for Beginners: Data Ingestion at Scale with S3 and Snowflake

The text discusses the importance of ETL (Extract, Transform, Load) operations in data engineering and highlights a common pattern involving moving data from an object storage like S3 to a data warehouse like Snowflake. It provides examples of use cases for this pattern, such as ingesting unstructured data delivered by external applications or performing complex transformations using Snowflake's compute power. The text also offers a tutorial on creating a best-practice daily ingestion pipeline to move data from S3 into Snowflake using Astro Free Trial and Apache Airflow, with only basic knowledge of Airflow and Python required.
