groupArrayLast

Syntax: groupArrayLast(max_size)(x)

Creates an array of last argument values. For example, groupArrayLast(1)(x) is equivalent to [anyLast (x)].

In some cases, you can still rely on the order of execution. This applies to cases when SELECT comes from a subquery that uses ORDER BY if the subquery result is small enough.
