How do you keep your ETL code and documentation up to date and consistent in the cloud?
Extract, transform, and load (ETL) is a process of moving data from various sources to a target system, such as a data warehouse or a data lake, in the cloud. ETL code is the set of scripts or programs that perform the data extraction, transformation, and loading tasks. ETL documentation is the collection of information that describes the data sources, the data flow, the data quality, the business rules, and the expected outcomes of the ETL process. Keeping your ETL code and documentation up to date and consistent in the cloud is essential for ensuring the accuracy, reliability, and maintainability of your data pipelines. In this article, we will share some best practices and tips on how to achieve this goal.
