Примечание
При большом количестве небольших столбцов этот формат неэффективен и, как правило, не имеет смысла его использовать.
Тем не менее по эффективности он не уступает формату JSONEachRow.
При разборе поддерживается любой порядок значений различных столбцов.
Допускается опускать некоторые значения, так как они считаются эквивалентными значениям по умолчанию.
В этом случае в качестве значений по умолчанию используются нули и пустые строки.
Сложные значения, которые могли бы быть заданы в таблице, не поддерживаются в качестве значений по умолчанию.
При разборе допускается добавление дополнительного поля tskv без знака равенства или значения. Это поле игнорируется.
При импорте столбцы с неизвестными именами будут пропущены,
если параметр input_format_skip_unknown_fields установлен в 1.
NULL форматируется как \N.
