Background
With the amount of sources and how different is consumed by the clients, using UDFs could help to support more sources:
Design
The UDFs are already supporting tables, and use yield to generate the values through streaming futures https://github.com/risingwavelabs/risingwave/blob/ed75502880af4fad364b9821ab85e7026188063d/src/expr/core/src/table_function/user_defined.rs#L93-L132.
This functionality could be translated to tables/sources to emit records when a new value is received from the UDF, using a sintax like
CREATE [TABLE|SOURCE ] .. AS <function_name> (param1, param2)Future Optimizations
