groupUniqArray
Syntax: groupUniqArray(x) or groupUniqArray(max_size)(x)
Creates an array from different argument values. Memory consumption is the same as for the uniqExact function.
The second version (with the max_size parameter) limits the size of the resulting array to max_size elements.
For example, groupUniqArray(1)(x) is equivalent to [any(x)].
