> It's possible to avoid any SQL querying and map some INSERT and MERGE statements to cache
operations in a way similar to that of UPDATE and DELETE - i.e. don't make queries when there
are no expressions to evaluate in the query and enhance update plans to perform direct cache
operations when INSERT and MERGE affect columns {{_key}} and {{_val}} only.
