        collection_name = cf.gen_unique_str(prefix)
        client_w.create_collection(client, collection_name, default_dim, consistency_level="Strong")
        # 1. alter default database properties before load
        properties = {"key1": 1, "key2": "value2", "key3": [1, 2, 3]}
        client_w.alter_database_properties(client, db_name="default", properties=properties)
        res1 = client_w.describe_database(client, db_name="default")[0]
        assert res1.properties.items() >= properties.items()
