Hey, I am working on Ray object store, and I would like to ask whether the copying of objects from one node to another happens in parallel for large objects. I saw that the objects are sent in chunks of configurable size, but does the raylet send chunks one by one or they can be sent in parallel?

I think they are sent / received in parallel.
