[jira] [Created] (IGNITE-6199) SQL: DML processor should send deltas instead of full values when possible

             Summary: SQL: DML processor should send deltas instead of full values when possible
                 Key: IGNITE-6199
                 URL: https://issues.apache.org/jira/browse/IGNITE-6199
             Project: Ignite
          Issue Type: Task
          Components: sql
    Affects Versions: 2.1
            Reporter: Vladimir Ozerov


Currently we send full values during DML operations. Instead, we should find the way to send only changed attributes. Chances that it will require adding versions of existing entries, or even the whole MVCC, to prevent inconsistent updates.
