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

             Summary: JDBC thin: support query cancellation
                 Key: IGNITE-5378
                 URL: https://issues.apache.org/jira/browse/IGNITE-5378
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov
             Fix For: 2.2


We need to support {{Statement.cancel()}} for thin JDBC driver. Ignite already able to cancel
queries on a server side, so we should simply create new request-response pair for this.

Special attention should be dedicated to precise specification semantics. Namely, query could
be started from the one thread, but cancelled from another. Hence, concurrency should be implemented
accurately.
