Reverse ETL

Reverse ETL is the process of copying data *from* a central data store (like a data warehouse or lakehouse) *back into* operational systems (like CRMs, marketing tools, or databases) where it can be used to drive business actions. While traditionally batch-oriented, streaming systems like RisingWave can potentially power real-time Reverse ETL use cases by sinking processed results directly into operational tools with low latency.
