Description
Description
($derivative is new in 5.0 as part of the Window Functions project, so this is a breaking change only for internal users.)
We made a small syntax change vs the Syntax doc: $derivative requires an explicit 'window' argument. Other window functions that accept a 'window' default to [unbounded, unbounded], but we thought this might be confusing default for $derivative.
Description of Linked Ticket
SERVER-54233 adds a new executor type for $derivative, but its not currently hooked up to the front end. The two main tasks for this ticket are to (1) register a $derivative parser and parse tree representation (window_function::Expression) and (2) build the new executor when appropriate. Then we should be able to write JS tests for the derivative function as well.
