> It would be useful if Spark SQL supported the {{max_by()}} SQL aggregate

> docs|https://prestodb.github.io/docs/current/functions/aggregate.html#max_by]:
> {quote}max_by(x, y) → [same as x]
> Returns the value of x associated with the maximum value of y over all input
> values.
> {quote}
> {{min_by}} works similarly.
> Technically I can emulate this behavior using window functions but the
> resulting syntax is much more verbose and non-intuitive compared to
> {{max_by}} / {{min_by}}.
