When it comes to data processing, ETL and ELT are two terms that often come up in discussions about data pipelines. But what exactly do these terms mean, and how do they differ? Letโ€™s dive deep into the world of ETL and ELT, and uncover which one reigns supreme in certain situations! ๐Ÿš€๐Ÿ“Š

  • ETL: Extract, Transform, Load
  • ELT: Extract, Load, Transform

Imagine youโ€™re preparing a big dinner. You have raw ingredients (the data) that need to be prepped (transformed), cooked (loaded), and finally served to the guests (delivered to your data warehouse). The method you choose to prep, cook, and serve your meal can either follow the traditional route (ETL) or a more modern approach (ELT).
