[jira] [Created] (IGNITE-6076) SQL: Local query should not go through map-reduce phase

Vladimir Ozerov created IGNITE-6076:
---------------------------------------

             Summary: SQL: Local query should not go through map-reduce phase
                 Key: IGNITE-6076
                 URL: https://issues.apache.org/jira/browse/IGNITE-6076
             Project: Ignite
          Issue Type: Task
          Components: sql
    Affects Versions: 2.1
            Reporter: Vladimir Ozerov
             Fix For: 2.2


Typical query execution consists of map and reduce phases. But if {{local}} flag is set, there is no need for splitting. Instead, we should execute the request in a single map phase, without involving reducer at all.
