Mysql 如何使我的GTFS查询运行得更快？,mysql,gtfs,Mysql,Gtfs,我正在尝试使用GTFS数据库，即RATP为巴黎及其郊区提供的数据库 数据集是巨大的。stop\u times表有1400万行 以下是表格模式： 我正试图以最有效的方式获得特定位置的可用路线。就我对GTFS规范的理解而言，以下是从我的数据（lat/lon）到路线的表格及其链接： stops | stop_times | trips | routes -----------+----------------+------------+-------------- lat

我正在尝试使用GTFS数据库，即RATP为巴黎及其郊区提供的数据库

数据集是巨大的。
stop\u times
表有1400万行

以下是表格模式：

我正试图以最有效的方式获得特定位置的可用路线。就我对GTFS规范的理解而言，以下是从我的数据（lat/lon）到路线的表格及其链接：

stops      | stop_times     | trips      | routes
-----------+----------------+------------+--------------
lat        | stop_id        | trip_id    | route_id
lon        | trip_id        | route_id   |
stop_id    |                |            |
为了清晰起见，我将我想要的东西分为三个步骤（实际上是上面四个表格之间的三个链接）进行汇编，并在本要点下发布：

下面是我如何创建这个脚本的

我能够在不到一秒钟的时间内快速找到步行距离（比如200米）内的所有站点。我使用：

$ . mysql.ini && time mysql -h $host -N -B -u $user -p${pass} $name -e "SELECT stop_id, (6371000*acos(cos(radians(48.824699))*cos(radians(s.stop_lat))*cos(radians(2.3243)-radians(s.stop_lon))+sin(radians(48.824699))*sin(radians(s.stop_lat)))) AS distance
FROM stops s
GROUP BY s.stop_id
HAVING distance < 200
ORDER BY distance ASC" | awk '{print $1}'

我怎样才能更快地得到这个结果？是否有更好的方法来浏览数据，而不是我所采用的路径
stops>stop\u times>trips>routes

这里的总时间大约是30秒，实际上是一个“查询”：“距离此位置200米的可用路线是什么？”。这太多了…

简单的回答是：使用表连接和索引

下面是一个较长的答案：

您在这里的想法是正确的，您对表之间的关系的理解是正确的。但是，通过要求DBMS匹配列表中的字段值（使用
中的WHERE…
），而不是将表连接在一起，您需要它做的工作比需要的多得多

您真正想要做的是将所有这些作为单个查询执行，使用
JOIN
子句将表链接在一起。尝试此操作，它将另外加入
日历
和
日历_日期
表，以将结果仅限于今天实际运行的路线：

SELECT DISTINCT r.id, r.route_long_name
  FROM (SELECT s.stop_id, (6371000 *
          acos(cos(radians(48.824699)) * cos(radians(s.stop_lat)) *
          cos(radians(2.3243) - radians(s.stop_lon)) +
          sin(radians(48.824699)) * sin(radians(s.stop_lat)))) AS distance
          FROM stops AS s) AS i_s
  INNER JOIN stop_times AS st ON st.stop_id = i_s.stop_id
  INNER JOIN (SELECT trip_id, route_id FROM trips AS t
                INNER JOIN (SELECT service_id FROM calendars
                              WHERE start_date <= '2014-09-09'
                                AND end_date >= '2014-09-09'
                                AND tuesday = 1
                              UNION
                                SELECT service_id FROM calendar_dates
                                  WHERE date = '2014-09-09'
                                    AND exception_type = 1
                              EXCEPT
                                SELECT service_id FROM calendar_dates
                                  WHERE date = '2014-09-09'
                                    AND exception_type = 2) AS c
                   ON c.service_id = t.service_id) AS t_r
    ON t_r.trip_id = st.trip_id
  INNER JOIN routes AS r ON r.route_id = t_r.route_id
  WHERE st.departure_time > '$now'
    AND i_s.distance < 200;
我使用的表模式显然是错误的，我应该自己构建它，或者至少在使用它之前分析它

我已将

我仍然需要对此模式进行一些优化

现在，此查询只需不到1-5秒：

SELECT
    s.stop_id,
    (6371000*acos(cos(radians(48.1128135))*cos(radians(s.stop_lat))*cos(radians(-1.6470705)-radians(s.stop_lon))+sin(radians(48.1128135))*sin(radians(s.stop_lat)))) AS distance,

    r.*,
    c.*

FROM stop_times st

LEFT JOIN stops s USING (stop_id)
LEFT JOIN trips t USING (trip_id)
LEFT JOIN routes r USING (route_id)

LEFT JOIN calendar c ON c.service_id = t.service_id 

where
    c.start_date <= 20140915
    and c.end_date >= 20140915
    and c.sunday = 1

    and st.departure_time > '15:00:00'

HAVING

ORDER BY st.departure_time ASC

选择

< /代码> 我只能告诉你，我用SQL尝试了同样的事情，它花了很长时间，所以我必须写一个脚本，首先在Perl（没有增益），然后在C++中（增益35×快）。我已经尝试过使用
LEFT-JOIN
，这花了我很长时间（实际上我不知道，我
Ctrl-C
ed了这个查询）。您的查询耗时53秒，这比我所有的查询加在一起要好得多。添加索引需要。。。好吧，现在已经过去了几分钟，但它们还没有被创建。敬请期待！嗯，我很困惑。我删除了
发车时间
上的索引，因为它们失败了（多个站点可能共享同一发车时间）。我继续写我的剧本，不到一分钟就有了结果。但是，您的查询将生成一个空结果集。为了清楚起见，请看一下这里：（不可否认，现在已经晚了很多，所以它搜索的出发时间比23h50晚，这意味着结果要少得多）实际上这是公平的。我使用硬编码为
18:30:00
的出发时间进行测试，我在36秒内得到了我们在问题中看到的结果。那么我在上面发布的查询到底是返回结果吗？我用一个新的索引定义更新了我的答案，希望它能作为一个覆盖索引，阻止MySQL对
stops
表进行完整扫描，我怀疑这是它目前花费大部分时间的地方。我要提到的另一件事是：我们的查询实际上应该加入
日历
和
日历日期
表，并将结果限制在今天运行的路由上。（请参阅。）实际上规范没有提到类型，因此我们只能假设
VARCHAR
。这超出了我的理解，因为整数键的速度要快得多。在
shapes
表中
shapept__________________;lon DECIMAL（8,6）
应该是
DECIMAL（9,6）
来解释
-180
的范围吗？（虽然这对于您拥有的数据来说可能不是必需的）您是对的，我确实在不久前注意到了这个bug并修复了它。我没有费心在这里编辑我的代码。这应该是一个评论，不回答问题。
