[jira] [Created] (IGNITE-3870) Keeping SQL query result set in off heap tire

Denis Magda created IGNITE-3870:
-----------------------------------

             Summary: Keeping SQL query result set in off heap tire
                 Key: IGNITE-3870
                 URL: https://issues.apache.org/jira/browse/IGNITE-3870
             Project: Ignite
          Issue Type: Task
            Reporter: Denis Magda
            Assignee: Sergi Vladykin


With the new off heap storage architectures (IGNITE-3477) it makes sense to improve a part of the system that prepares an SQL query result set in a such a way:
- result set should consist of wrappers objects that incorporate off heap pointers to fields and values stored off heap;
- during the time the result set is being sent over the wire we shouldn't move fields and values from off heap to Java heap but rather implement a solution that will allow us to pass an off heap pointer to a sockets output stream. Probably this can be done by leveraging Java's DirectBuffers.
