What are the Best Open Source ETL Tools?
The best open source ETL tools are crucial resources that help organizations adeptly handle their data. They do so by facilitating the extraction, transformation, and loading (ETL) of data from varied sources into a centralized repository.
This is a pivotal process for data integration, warehousing, and analytics. Open Source ETL tools have garnered immense popularity across businesses of all scales because they are typically free or low-cost, highly customizable.
The ETL process is divided into three main stages —
Extract
