Ultimately Redis just stores bytes, there's no reason you couldn't put arrow formatted data in it (or in Olric, as I understand it).

I do wish plasma wasn't dead/dying though. There is a huge gap in the (extremely crowded) key-value store space for zero-copy shared memory IPC. I assume it doesn't get built because it's not very "cloud native," but such a thing would be undeniably useful.
