Igor Sapego created IGNITE-4488:
-----------------------------------

             Summary: ODBC: First query execution takes much more time than any subsequent
                 Key: IGNITE-4488
                 URL: https://issues.apache.org/jira/browse/IGNITE-4488
             Project: Ignite
          Issue Type: Bug
          Components: odbc, platforms
    Affects Versions: 1.8
            Reporter: Igor Sapego
            Assignee: Igor Sapego
             Fix For: 2.0


When we perform SQL query on small dataset just to measure latency, the very first call takes much more time to execute than the same subsequent requests (~70ms vs ~10ms).

The same behavior can be observed with C++ client.
