Passing a tuple of keys and value ​​arrays is identical to passing two arrays of keys and values. The number of elements in `key` and `value` must be the same for each row that is totaled. Returns a tuple of two arrays: keys in sorted order, and values calculated for the corresponding keys. Example: ``` sql SELECT minMap(a, b) FROM values('a Array(Int32), b Array(Int64)', ([1, 2], [2, 2]), ([2, 3], [1, 1])) ``` ``` text ┌─minMap(a, b)──────┐ │ ([1,2,3],[2,1,1]) │ └───────────────────┘ ```
