Steven Hawkins commented on TEIID-3638:
---------------------------------------
Analytical functions are just like any other query construct to us. If the optimizer can
push them down, then they will be pushed. Otherwise they will be executed in the engine.
https://docs.jboss.org/author/display/TEIID/Expressions has a section on supported window
functions, and the full grammar is in
https://docs.jboss.org/author/display/TEIID/BNF+for+SQL+Grammar
Can you clarify what enhancements/documentation you are looking for?
