If you’re a data scientist or data engineer, this might sound familiar while working on ETL projects:

• Switching between multiple projects is a hassle
• Debugging others’ code is a nightmare
• Spending a lot of time solving non-business-related issues

SETL (Spark ETL, pronounced "settle") is a Scala framework that helps you structure your Spark ETL projects, modularize your data transformation logic and speed up your development.
