---------------------------------------
Summary: GridUnsafe: implement specialized methods for every kind
of copy operation.
Key: IGNITE-4295
URL: https://issues.apache.org/jira/browse/IGNITE-4295
Project: Ignite
Issue Type: Task
Components: general
Affects Versions: 1.8
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Priority: Minor
Fix For: 2.0
1) copy(OFFHEAP, HEAP)
2) copy(HEAP, OFFHEAP)
3) copy(OFFHEAP, OFFHEAP)
4) copy(HEAP, HEAP)
5) copy(T[], T[]) must be avoided and replaced with System.arrayCopy().
6) Add optional threshold. If we copy too small memory chunk which size is
below the threshold, then resort to byte-by-byte copying, as it will be faster.
E.g. on PowerPC with OpenJDK 8, copying of <100 bytes of data is faster on
byte-by-byte basis.
