In order to show the connection topology of Milvus, we have the nodes_info in response. nodes_info is a list and every item in list indicates a node in Milvus cluster. Every item has a identifier which is unique in nodes_info. The identifier can be used in connected content, for example, proxy has connected to root coordinator and data coordinator, so the connected content is [1, 2], 1 is the identifier of root coordinator, 2 is the identifier of data coordinator.
