Review Comment:
It is because we have divided it at the proto level: in proto, query and
command are different.
The primary reason for dividing is, query runs and return rows. Command
apply a state change without return anything (except exceptions probably).
Maybe there is better way to mode all of these. For example, will Catalog
API fit into this model? I am still thinking about it but do not have a clear
answer now.
