I korthet

Reverse ETL is moving processed data from data warehouses back to operational systems (CRM, marketing tools, databases) to activate insights. Used by data engineers, analytics engineers, and ops teams. Salary impact $130-200k mid-level. Takes 4-6 months to master. Sits between data engineering and analytics engineering.

Vad är Reverse ETL Pipeline

Reverse ETL is the process of moving data from a central data warehouse back to operational systems (CRM, email platforms, analytics tools, databases). Traditional ETL pulls data into warehouses; Reverse ETL activates insights by sending processed data back out. A typical example: sync customer segments computed in the warehouse back to Salesforce, so sales reps see them in real-time. Reverse ETL combines data engineering (pipeline design), SQL/analytics (data transformations), and API integration (pushing to external systems).
