Question

我在php中创建 WebService ，我的网站将用它来查询 Ajax 调用的信息。

首先，我使用内置的php mysql lib以标准方式完成它，并手动编写所有查询并在 MySQL Workbench 中创建整个数据模型，依此类推。这非常耗时，如果我不得不改变数据模型，之后一切都会变得非常复杂，所以我决定寻找 PHP ORM ，我发现 RedBean 在我看来，这是纯粹的魔法和快乐。

除了我在性能问题上非常困难。我的网站是一个网站，供用户创建自己的电视连续剧列表。我查询一个系列的外部源并将其插入我的数据库中，如果它还没有，否则我从我自己的数据库中得到它。

我从这个外部来源回来的xml列出了系列，季节，剧集等等，我把这一切都存储起来。

function InsertSerie($serie) {
    $serieBean = $this->CreateSerieBean($serie->Series);
    $genreBeans = $this->CreateGenreBeans($serie->Series->Genre);
    $actorBeans = $this->CreateActorBeans($serie->Series->Actors);
    $episodeBeans = array();
    foreach ($serie->Episode as $episode) {
        $episodeBean = $this->CreateEpisodeBean($episode);
        $seasonBean = $this->CreateSeasonBean($episode);
        $writerBeans = $this->CreateWriterBeans($episode->Writer);
        $guestBeans = $this->CreateActorBeans($episode->GuestStars);
        $directorBeans = $this->CreateDirectorBeans($episode->Director);
        R::associate($episodeBean, $seasonBean);
        foreach ($writerBeans as $bean) {
            R::associate($episodeBean, $bean);
        }
        foreach ($guestBeans as $bean) {
            R::associate($episodeBean, $bean);
        }
        foreach ($directorBeans as $bean) {
            R::associate($episodeBean, $bean);
        }
        $episodeBeans[] = $episodeBean;
    }

        R::associate($serieBean, $bean);
    }
    foreach ($episodeBeans as $bean) {
        R::associate($serieBean, $bean);
    }
}

function CreateGenreBeans($genres) {
    if(empty($genres)) { return; }
    $genre = explode("|", $genres);
$genreBeans = array();
foreach ($genre as $g) {
    if($g != '') {
            $genreBeans[] = $this->CreateGenreBean($g);
        }

    if(empty($actors)) { return; }
    $actor = explode("|", $actors);
$actorBeans = array();
foreach ($actor as $a) {
    if($a != '') {
            $actorBeans[] = $this->CreateActorBean($a);
        }
    }
    return $actorBeans;
}

function CreateActorBean($actor) {
    $bean = R::dispense('actor');
    $bean->name = (string)$actor;

    return $writerBeans;

function CreateWriterBean($writer) {
    $bean = R::dispense('writer');
    $bean->name = (string)$writer;
    return $bean;
}

function CreateSerieBean($serie) {  
    $bean = R::dispense('serie');
    $bean->serie_id = (string)$serie->id;
    $bean->airs_day_of_week = (string)$serie->Airs_DayOfWeek;

function CreateSeasonBean($episode) {
    $bean = R::dispense('season');
    $bean->season_id = (string)$episode->seasonid;

    $bean->rating = (string)$episode->Rating;
    $bean->rating_count = (string)$episode->RatingCount;
    $bean->last_updated = (string)$episode->lastupdated;
    return $bean;
}

问题是插入一个系列需要大约5分钟，并且它也会插入重复项，而R::freeze();也无法帮助提高性能。

问：我如何解决这个问题，我该怎么做才能让redbean更好地运行，我可以用自己的代码做些什么来让它更好用，或者我应该只使用不同的解决方案/方法框架等吗

尝试了建议的共享列表但结果相同。

function InsertSerie($serie) {
    $serieBean = $this->CreateSerieBean($serie->Series);
    ...
    foreach ($serie->Episode as $episode) {
        $episodeBean = $this->CreateEpisodeBean($serieBean ,$episode);
        ...
        $this->CreateDirectorBeans($serieBean, $episode->Director);
        $serieBean->sharedEpisode[] = $episodeBean;
    }
    R::store($serieBean);
}

function CreateDirectorBeans($bean, $directors) {
    if(empty($directors)) { return; }
    $director = explode("|", $directors);
    foreach ($director as $d) {
        if($d != '') {
            $bean->sharedDirector[] = $this->CreateDirectorBean($d);
        }
    }
}

function CreateDirectorBean($director) {
    $bean = R::dispense('director');
    $bean->name = (string)$director;
    return $bean;
}
    ....

Answer 1

我终于找到了如何将执行时间从5分钟降低到大约11秒，仍然需要花费大量时间，但考虑到数据量和工作量，我认为它对硬件有利。

我添加了这些代码行

R::Begin();
R::associate($bean1, $bean2);
...
R::commit();

现在它收集所有工作并在一个大的事务中执行它，如工作单元模式。另外为了防止插入重复，我转而使用

$bean = R::findOrDispense($type, $sql, $values);

然后我只返回bean，如果它已经存在，如果不是我创建一个新的并返回它。

您是否尝试过使用共享列表而不是循环关系？

$serieBean->sharedActor[] = $actorBeans;
$serieBean->sharedEpisode[] = $episodeBeans;
