Delivery Stream is focused on delivering data to various storage or analytics destinations with optional data transformation, ideal for near real-time ETL (Extract, Transform, Load) processes.

Data Stream is more about ingesting and processing real-time data at low latency, where you can build custom applications that consume and process the data in real time.

Replacing protobuf with Open api spec will allow to deprecate Datumgen and allow same strong type checking

Replacing with Kinesis data stream SDK in client can deprecate the need to maintain our own server.

Reverse ETL: Census specializes in reverse ETL (Extract, Transform, Load), which is the process of moving data from a data warehouse back into operational systems. This is the opposite of traditional ETL, which moves data into the warehouse. Reverse ETL ensures that the most current and relevant data is available in the tools used by different business teams.
