[?] Use operator form of MaximalBy[] also specifying the number of items?

Questions
1

I would like to write a Query[] to pick out say the top three items from a dataset.

I start with this

mydata[MaximalBy[#Value &]]

which gives me the data row with the largest “value”. To get the top 3 I would need an operator form of MaximalBy that allows me to specify the number of items (e.g. 3), but according to the documentation this is not available. Is there an elegant workaround or do I need to do this?

mydata[SortBy[#Value &] /* Reverse /* Part[1 ;; 3]]

Many thanks

Using a pure (or anonymous or lambda) function:

MaximalBy[#, #Value &, 3] &

should work.

It works. Thank you Sander
