Learn what reverse ETL is and how it differs from traditional ETL. Traditional ETL moves data into the data warehouse. Reverse ETL moves data the other way – from your warehouse back into business applications like CRMs, ERPs, ad platforms and support tools.
Reverse ETL closes the loop on the modern data stack. Once data is cleaned and modeled in the warehouse, reverse ETL operationalizes it – syncing customer scores back to your CRM, syncing financial data to your accounting system, or updating audiences in ad platforms.
This video introduces the core concepts: sources (warehouse tables and SQL queries), destinations (business apps), field mapping, sync modes (insert, update, upsert), and scheduling.
