org.apache.flink.runtime.memorymanager.SimpleMemorySegment
This class represents a piece of memory allocated from the memory manager. The segment is backed by a byte array and features random put and get methods for the basic types that are stored in a byte-wise fashion in the memory.

    CheckedMemorySegment checkedSegment = new CheckedMemorySegment(segmentArray);
    long elapsedChecked = timePutByteArrayChecked(checkedSegment, sourceArray, numValues, rounds);
    checkedSegment = null;
    
    Arrays.fill(segmentArray, (byte) 0);
    SimpleMemorySegment directSegment = new SimpleMemorySegment(segmentArray);
    long elapsedDirect = timePutByteArrayDirect(directSegment, sourceArray, numValues, rounds);
    directSegment = null;
    
    Arrays.fill(segmentArray, (byte) 0);
    UnsafeMemorySegment unsafeSegment = new UnsafeMemorySegment(segmentArray);
