--------------------------------------------------
[~danny0405] I did not understand when you say SqlReturnTypeInference
DECIMAL_SUM is pluggable.
If i want to use different rules for sum return type inference than the one
already present in the same, how would i achieve that as a client of Calcite?

> Currently decimal product and quotient return types are derived through type
> factory, this allows clients to override the return type if they so desire.
> But decimal sum is embedded in return types, also decimal mod does not have a
> return type inference defined.
> This task is to derive all of the return types through type factory, so that
> clients can override if they wish to.
