LGTM overall, but can we return Err rather than use todo! and unimplemented!?

@andygrove just saw this. Yes. Question, what kind of error do we want to thrown when something happens like this you think? Should we add one for "UnImplemented"?

Yes, in the core DataFusion crate we have DataFusionError::NotImplemented(String) so would be good to be consistent with that.

CI is failing due to rate limits trying to consume the protoc github actions plugin. Will make another commit later in hopes this is resolved. If this continues to happen we might want to investigate moving to a manual protoc installation. That is much more messy but might be necessary if this keeps happening. Feel like that should happen in another PR however.
