Missing Native Query documentation for Window Functions #18872
Description
Description
Window functions have been GA in druid since October 2024, but the current documentation only covers druid SQL.
It would be great to extend the documentation to cover the windowOperator query type in native queries.
Motivation
The native query syntax is much friendly for programatically generating queries, we'd like to use window functions but the lack of documentations means we need to figure out the syntax by EXPLAIN'ing queries or reading the druid source.
