             Summary: Thin 3.0. Sql. Cleanup resources when user cancels query.
                 Key: IGNITE-25052
                 URL: https://issues.apache.org/jira/browse/IGNITE-25052
             Project: Ignite
          Issue Type: Bug
          Components: sql, thin client
            Reporter: Pavel Pereslegin


Currently client resource (ResultSet) is cleared in two cases
1. User explicitly call {{close()}} on ResultSet.
2. After fetching last page.

At the same time, javadoc of {{CancelHandle#cancel()}} contains the following statement
{noformat}
after the process has been terminated and the resources associated with that process have been freed
{noformat}

It is necessary to implicitly clean up the client's resources when a request is cancelled.

Note: need to look at what other cases it is worth doing automatic resource cleaning (probably in the case of an error in ClientSqlCursorNextPageRequest).
