«Разделяй и властвуй» для OpenStreetMap мира в PostgreSQL

Продолжу рассказ «Как поместить весь мир в обычный ноутбук: PostgreSQL и OpenStreetMap» секретами о геоданных OpenStreetMap, на которых множество компаний построили бизнес, но не все делятся подробностями… Что ж, сегодня приоткроем завесу!

База данных в PosgreSQL после загрузки из дампа занимает больше 587 GB. Это уже по меркам СУБД большая база и одна огромная таблица на каждый тип объектов не сработает. Для управляемости такие данные надо секционировать, хорошо что PostgreSQL поддерживает декларативное секционирование данных. Осталось лишь придумать как разделить географические данные. После поисков и сравнений мне на помощь пришла иерархическая гексагональная геопространственная система индексирования H3 Все это было реализовано в моем проекте openstreetmap_h3.

Из систем геопартиционирования рассматривал варианты:

  • деление по административным границам/странам. Вариант вычислительно емкий на этапе подготовки данных и очень условный, так как политическая ситуация и границы меняются. В каких-то регионах внутренние границы условны, как например в ЕС.

  • разбиение прямоугольной сеткой. Не особо хорошо работает из-за искажений проекции сферических координат на плоскость, хотя и самый вычислительно простой!

  • иерархическая система S2, некогда популярная благодаря компании разработчику. Использует квадратные ячейки и в задачах агрегации данных и роутинга хуже чем шестигранная ячейка.

  • иерархическая H3. И выбор был сделан в пользу последней, так как эта иерархическая система индексирования H3 имеет преимущества в сохранении расстояний (приблизительно одинаковый радиус сегмента в любой точке земного шара), отлично подходит для задач маршрутизации, библиотеки для работы с H3 хорошо поддерживаются и постоянно развиваются и доступны для PostgreSQL/JVM.

Дамп планеты официально публикуется OSM в форматах XML и PBF. XML формат слишком объемный и многословный для геоданных планеты, а PBF — бинарный формат на основе protobuf с секциями (обычно скомпрессированными) где в каждой отдельной секции сохраняется только один тип объекта: node, way, relation отсортированные в порядке их ID. К тому же строки хранятся в каждой секции в StringTable в порядке частоты использования и теги на них ссылаются по номеру. Все это позволяет OSM компактно хранить геометрию, метаданные и получить хорошую компрессию данных блока.

Даже если мы идеально секционируем все данные OpenStreetMap каким-либо из алгоритмов, то останутся еще особенности данных и формата, которые лучше учесть сразу. Первое — что линии хранятся ссылками на точки, а не реальными значениями координат, поэтому нужно собрать ways из объектов nodes на этапе подготовки скриптов и не загружать nodes в таблицу без тегов или такие nodes на которые не ссылаются объекты relations. Это изначально делал в своем коде на java, в позже отдал на откуп обработку исходного PBF утилите osmium add-locations-to-ways --keep-member-nodes --output-format pbf,pbf_compression=none. А второе, что самый большой объем данных приходится на объекты ways после сборки и хотелось бы узнать эвристику по данным. С чем нам придется работать чаще всего?

osmworld=# select count(*), 
                  count(tags->'building')*100.0/count(*) as "building_%", 
                  count(tags->'highway')*100.0/count(*) as "highways_%"
            from ways;
   count   |     building_%      |     highways_%

Получается, что от общего количества линий в OpenStreetMap: 59% — это здания, 24% — дороги и тропы. Так что выделим признаки типа в отдельные колонки и если понадобится позже, то сможем вынести эти данные в субпартиции. Если для задач аналитики не нужны здания и дороги, то их импорт в базу можно отключить, задав параметры утилиты skip_buildings и skip_highwayсоответственно.

Парсинг формата PBF отдадим на откуп библиотеке org.openstreetmap.osmosis: osmosis-pbf2, но вот с секциями немного позже пошаманим для увеличения параллелизма парсинга и обработки данных. Например, planet-220704.osm.pbf дамп содержит 1255 секций. То, как работает osmosis-pbf2 меня не устраивает и написал свою реализацию доступа к секциям данных в программе (Splitter, PbfBlobOffsets). Это позволяет пропорционально числу секций распараллелить парсинг и обработку данных.

Эти эвристики помогли мне разбить ways, nodes, multipolygon каждый на сотню партиций…

Что же в openstreetmap_h3 «под капотом»

Если настолько глубоко эта тема не интересует, то смело пролистывайте статью до картинок!

Когда решил выбрать уровень 3 для индекса H3, то теоретический предел числа партиций будет равен 41162, а средняя длина ребра шестигранника 59.811 км. Опытным путем выяснил что на уровне 2 есть огромные партиции в Европе, а уровень 4 уже слишком детализированный и индексы не удастся закодировать как int2 в базе данных, а мы стремимся сохранить компактность объема данных и хорошую производительность решения.

Что же делать, если линия пересекает несколько ячеек сетки разбиения H3? В первоначальной версии ПО я выставлял значение партиции в null, теперь же использую «костыль» — значение 32767(так как некоторые колоночные БД хитрят с null значениями и не ведут отдельную битовую карту для них, а используют максимальное значение из типа shot int), и заполняем на этапе импорта в PostgreSQL поле типа массив h3_3_multi_regions, где перечислены все индексы которые входят в эту линию.

Все это замечательно, только PostgreSQL позволяет эффективно работать только с сотнями партиций на таблицу, а у нас их получилось десятки тысяч. Значит надо объединять диапазоны h3_3 — тут нам помогут диапазоны значений в партициях и укрупнение партиций PartitionSplitter.java. Будем пытаться собрать h3 уровня 3 партиции в более крупные уровня 2 и при превышении порога thresholdPercentFromMaxPartition в долях числа линий от самой крупной партиции, будем создавать новую партицию:

    public static List distributeH33ByPartitionsForWays(Map waysSizeStat, double thresholdPercentFromMaxPartition){
        Map h3RangeInH2 = null;
        Map h33to2 = null;
        try {
            h3RangeInH2 = getH3RangeInH2();
            h33to2 = parseH33to2();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        Map finalH33to = h33to2;
        Map sumByH2 = new TreeMap<>(waysSizeStat.entrySet().stream().map(entry -> new AbstractMap.SimpleImmutableEntry<>(finalH33to.get(entry.getKey()), entry.getValue())).collect(Collectors.groupingBy(Map.Entry::getKey,
                Collectors.summingLong(Map.Entry::getValue))));
        long maxPartitionSize = (long) (sumByH2.values().stream().max(Comparator.comparingLong(Long::longValue)).get()* thresholdPercentFromMaxPartition);
        long currentSum=0;
        short lowerBound=LOWER_H3_3_BOUND;
        int partitionNumber=0;
        List partitions = new ArrayList<>();
        for(Map.Entry entry: sumByH2.entrySet()){
            Short h2 = entry.getKey();
            Partition nextRange = h3RangeInH2.get(h2);
            if(currentSum>0 && currentSum+entry.getValue()>=maxPartitionSize){
                short maxRangeOfInterval = nextRange.getMinRange();
                partitions.add(createPartition(waysSizeStat, currentSum, lowerBound, partitionNumber, maxRangeOfInterval));
                System.out.println(partitionNumber++ +"\t["+lowerBound+","+ maxRangeOfInterval +")\t"+currentSum+"\t"+(maxRangeOfInterval-lowerBound));
                lowerBound=nextRange.getMinRange();
                currentSum=entry.getValue();
                continue;
            }
            currentSum+=entry.getValue();
        }
        if(currentSum!=0){
            short maxRangeOfInterval = HIGH_H3_3_BOUND;
            partitions.add(createPartition(waysSizeStat, currentSum, lowerBound, partitionNumber, maxRangeOfInterval));
            System.out.println(partitionNumber+"\t["+lowerBound+","+maxRangeOfInterval+")\t"+currentSum+"\t"+(maxRangeOfInterval-lowerBound));
        }
        return partitions;
    }

Для целей агрегации и работы с пешеходными дистанциями я добавил к OSM данным значения H3 индекса уровня 8. Средняя площадь такой ячейки около 0.737 км2 и это последний уровень который можно закодировать в int4. Но такие индексы будем считать только для линий длиной меньше 3 км по алгоритму:

        Set wayIntersectionH38Indexes = null;
        if(!isOneH38 && distanceMeter < 3000.0){
            wayIntersectionH38Indexes = Arrays.stream(h38SourceIdxs).mapToObj(CompactH3::serialize8).collect(Collectors.toCollection(TreeSet::new));
            for (int i = 0; i < h38SourceIdxs.length - 1; i++) {
                wayIntersectionH38Indexes.addAll(h3Core.gridPathCells(h38SourceIdxs[i],h38SourceIdxs[i+1]).stream().map(CompactH3::serialize8).collect(Collectors.toSet()));
            }
            if(closed){
                wayIntersectionH38Indexes.addAll(h3Core.gridPathCells(h38SourceIdxs[0],h38SourceIdxs[h38SourceIdxs.length-1]).stream().map(CompactH3::serialize8).collect(Collectors.toSet()));
                wayIntersectionH38Indexes.addAll(h3Core.polygonToCells(wayNodes.stream().map(wayNode -> new LatLng(wayNode.getLatitude(), wayNode.getLongitude())).collect(toList()), null, 8).stream().map(CompactH3::serialize8).collect(Collectors.toSet()));
            }
            if(wayIntersectionH38Indexes.size() == 1){
                if(wayIntersectionH38Indexes.iterator().next().equals(h38)){
                    wayIntersectionH38Indexes = null;// save only center h38 as it duplicate it
                }
            }
        }

Схема базы данных

Описание полей объектов идут в порядке выравнивания объектов фиксированной и переменной длинны, чтобы минимизировать объем данных на диске. В этих оптимизациях мне помогла утилита postgres_dba. Структуру таблиц старался сделать максимально близко к pgSnapshot схеме из Osmosis.

    h3_8 integer NOT NULL,
    tags hstore,

После импорта список партиций для ways…
