What is ETL?

ETL (Extract, Transform, Load) is often associated with machine learning. While crucial there, ETL is fundamental to the operational integrity of nearly all modern software applications.

ETL, a three-step process, varies in complexity for each stage depending on the application. To automate ETL, the process must be carefully engineered and diligently maintained.

An ETL pipeline as part of a system may have even more complex structrure:

Our goal is to develop a maintable and scalable ETL pipeline. Further, we'll discus architectures and techniques for developing robust and scalable ETL pipelines.
