[jira] [Created] (IGNITE-20763) Sql. Clean up query execution

Konstantin Orlov created IGNITE-20763:
-----------------------------------------

             Summary: Sql. Clean up query execution
                 Key: IGNITE-20763
                 URL: https://issues.apache.org/jira/browse/IGNITE-20763
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Konstantin Orlov
            Assignee: Konstantin Orlov
         Attachments: flamegraph.html

According to flamegraph, QueryTaskExecutor spent more time doing unnecessary staff (like instantiating VoidLogger or filling stack traces on happy path execution flow) rather than on query itself in case of primitive queries like {{SELECT * FROM TABLE(system_range(0, 1))}}.
