Этот JSON хранится в базе данных Cassandra в столбце «данные» (идентификатор - это uuid, а столбец данных - JSON json.dumps(result))):
INSERT INTO monitor (id, data) VALUES (%s, %s)
Хорошо, я делаю SELECT, чтобы получить все строки, хранящиеся в базе данных. Выбор:
SELECT data from monitor
И получите:
<cassandra.cluster.ResultSet object at 0x7f1610771fd0>
Я создам Pandas Dataframe с этим JSON, но я не знаю, как я могу это сделать ...
Я пытаюсь составить список со строками (rs = list(rows)) и вывести rs Это результат:
Row(data='[{"rss": ...
К вашему сведению: Структура данных, которую я создам, должна иметь следующую структуру:
mac | имя | desc | лат | Инг | lrrt
Спасибо !!!
