ETL (Extract, Transform, Load): The traditional approach, where data is transformed before loading into the warehouse.
ELT (Extract, Load, Transform): Has become more popular, as it allows raw data to be loaded first, then transformed based on analytical needs.
Why ELT is better for modern analytics:
- More flexible and scalable, especially with cloud-based platforms like Snowflake.
- Allows businesses to keep raw data intact for future analysis.
- ELT is more efficient for handling large volumes of unstructured data.
Snowplow’s pipeline follows the ELT approach, enabling fast and scalable processing of event data directly into platforms like Snowflake.
