-------------------------------------------

             Summary: Optimize DML for fast INSERT and MERGE
                 Key: IGNITE-4490
                 URL: https://issues.apache.org/jira/browse/IGNITE-4490
             Project: Ignite
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 1.8
            Reporter: Alexander Paschenko
            Assignee: Alexander Paschenko
             Fix For: 1.8


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 _value only.
