Насколько многомерным может быть многомерный точный индекс?

Вот, например, Milvius(DiskANN) рассчитан на вектора размерности до 32 768 , но это приближенный поиск. Но как насчёт поиска точного? В данной статье рассматривается работоспособность 1024 мерного индекса, хранилищем которого служит обычное B-дерево (насколько вообще может быть обычным такое дерево). Используемый диск - вполне себе “железный” старый добрый WD Purple, оперативная память сознательно ограничена 8 Гб. Можно ли что-то из этого выжать на рядовом десктопе за приемлемое время?
