Wes McKinney commented on ARROW-2127:
-------------------------------------
One way might be to introduce a {{Move}} request and a {{Copy}} request. If the
source is CPU and target is GPU (or vice versa), then it would transfer across
devices
> [Plasma] Transfer of objects between CPUs and GPUs

> It should be possible to transfer an object that was created on the CPU to
> the GPU and vice versa. One natural implementation is to introduce a flag to
> plasma::Get that specifies where the object should end up and then transfer
> the object under the hood and return the appropriate buffer.
