-----------------------------------
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.
