Thanks for the review! Currently, such behavior of aggregate functions cannot be fixed because Drill does not know the input type of the function and rewrites it using `SUM` and `COUNT` aggregate functions. For regular types, it is ok, since results of these intermediate agg calls may be reused, but for decimals due to type inference rules, intermediate calculations on the results of agg calls may cause overflow.
