Hi, I have seen it written in the documentation that standard cluster is recommended for a single user. But why ? What is meant by that ? Me and one of my colleagues were testing it on the same notebook. Both of us can use the same standard all purpose cluster in the same notebook at the same time. It is just that we could not execute the same cell at the same time but that is reasonably normal.

But if two persons can use the same standard all purpose cluster in the same notebook at the same time, then why it is recommended for single user ? Does that mean that we should select high concurrency cluster when multiple people are collaborating in the same notebook at the same time for simple data read and write experiments ?
