примечание
Когда есть большое количество мелких колонок, этот формат неэффективен, и в общем нет причин его использовать.
Тем не менее, он не хуже, чем формат JSONEachRow по эффективности.
Для парсинга поддерживается любой порядок значений разных колонок.
Допускается пропуск некоторых значений, так как они считаются равными своим значениям по умолчанию.
В этом случае нули и пустые строки используются в качестве значений по умолчанию.
Сложные значения, которые могли бы быть указаны в таблице, не поддерживаются в качестве значений по умолчанию.
Парсинг позволяет добавить дополнительное поле tskv без знака равенства или значения. Это поле игнорируется.
При импорте колонки с неизвестными именами будут пропущены,
если настройка input_format_skip_unknown_fields установлена в 1.
NULL форматируется как \N.
