Review Comment:
Instead of caching the dataframe, we could also return the results and put
them in a client side local relation. The chance that folks are using the
results of a sql command for further processing is very very small.
BTW I do think that a remote dataframe is useful to have (it is very useful
for use cases like input stabilization, dataframe sharing, ...) but I don't
think we need it in this particular case.
