A feature request question about distributed GNN training

I have a question about how the features are transferred between multiple training machines.
For example, if machine A needs to read 10 graph nodes’ features from machine B, will A request 10 times (each time only request one node’s feature) to machine B or request only once to machine B? What’s the unit of request to another machine?

It only makes one request per minibatch per machine.
