Ruifeng Zheng commented on SPARK-41319:
---------------------------------------
I thought we need dedicated proto message for `when(...).otherwise(...)`, but I
just found that we have `CaseWhen` in FunctionRegistry, so maybe we can still
use `UnresolvedFunction` to express this.
I will update the status when I have more findings.
