Summary: SQL: optionally do not copy offheap rows for local SqlQuery Key: IGNITE-6945 URL: https://issues.apache.org/jira/browse/IGNITE-6945 Project: Ignite Issue Type: Task Security Level: Public (Viewable by anyone) Components: sql Reporter: Vladimir Ozerov Assignee: Taras Ledkov Fix For: 2.4 Currently when iterating over rows we eagerly materialize them [1]. If key or value are large enough, we could loose a lot of time on offheap-heap copying. To partially mitigate this, we can do the following: 1) Add new flag {{SqlQuery.localNoCopy}} which is applicable only for local queries. 2) When enabled we will not copy final {{_KEY}} and {{_VAL}} columns to heap. but rather wrap them into {{BinaryOffheapObjectImpl}} 3) These rows must be released when query iterator switches to the next row.
