------------------------------------
Summary: Optimization: for SQL indexes implement comparison using
offheap pointer
Key: IGNITE-4672
URL: https://issues.apache.org/jira/browse/IGNITE-4672
Project: Ignite
Issue Type: Task
Components: cache
Reporter: Semen Boikov
Assignee: Konstantin Dudkov
Fix For: 2.0
Currently for objects comparison in sql indexes we copy full row data on heap,
but when index is created on BinaryObject's field and object offheap address is
known then it is possible do comparison withput on heap copy and object
instantiation. Prototype is implemented in branch ignite-3477-offheap-cmp.
Note: IGNITE-4629 partially fixes issue with comparison, but it is not possible
to use this optimization in all cases.
