Jingsong Lee updated FLINK-11724:
---------------------------------
Description:
Blink new binary format is based on MemorySegment.
Improve MemorySegment to provide copyToUnsafe copyFromUnsafe and equalTo.
1.copyUnsafe: If we want to copy int[] data into MemorySegment, we can only use
int to set Int one by one, which is inefficient. We can copyFromUnsafe directly.
2.equalTo: Provide an efficient equalTo.
was:

int offset2, int len), copyToUnsafe copyFromUnsafe
2.Introduce MemorySegmentWritable to let DataOutputView direct copy to internal
bytes.
