The `join_node_request` and `join_node_response` RPCs are added: - `join_node_request` is sent from the joining node to any node in the cluster. It contains some initial parameters that will be verified by the receiving node, or the topology coordinator - notably, it contains a list of cluster features supported by the joining node. - `join_node_response` is sent from the topology coordinator to the joining node to tell it about the the outcome of the verification.
