[jira] [Created] (IGNITE-10559) MVCC TX: Use extracted partitions to reduce target nodes for Query Update

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

             Summary: MVCC TX: Use extracted partitions to reduce target nodes for Query Update
                 Key: IGNITE-10559
                 URL: https://issues.apache.org/jira/browse/IGNITE-10559
             Project: Ignite
          Issue Type: Task
          Components: mvcc
            Reporter: Igor Seliverstov


We may avoid "query reduce" step on update queries without sorting/grouping by simply sending them to all data nodes and executing update operation locally. Using extracted from SQL partitions will reduce target nodes count and save resources.
