>>> connections.connect(host="localhost", user="root", password="Milvus")
>>> client = MilvusClient(uri="http://localhost:19530", user="root", password="Milvus")
>>> client.create_collection("col1", dimension=128)

>>> db.create_database("jubing")
>>> role = Role("jubing_owner")
>>> role.create()
>>> utility.list_roles(True)
RoleInfo groups:
- RoleItem: <role_name:admin>, <users:()>
- RoleItem: <role_name:jubing_owner>, <users:()>
- RoleItem: <role_name:public>, <users:()>
>>> utility.create_user(user="jubing_owner", password="Milvus")
>>> role.add_user("jubing_owner")
>>> utility.list_roles(True)
RoleInfo groups:
- RoleItem: <role_name:admin>, <users:()>
- RoleItem: <role_name:jubing_owner>, <users:('jubing_owner',)>
- RoleItem: <role_name:public>, <users:()>
>>> role.list_grants()
GrantInfo groups:
>>> role = Role("jubing_owner")
>>> role.create_privilege_group("CollectionGroupA")
>>> role.add_privileges_to_group("CollectionGroupA", ["Load"])
>>> role.grant_v2("CollectionGroupA", "col1")
>>> role.list_grants()
GrantInfo groups:
- GrantItem: <object:Global>, <object_name:col1>, <db_name:default>, <role_name:jubing_owner>, <grantor_name:root>, <privilege:CollectionGroupA>
