LaravelでCollection型のデータを作ってバルクインサートする

Posted at

それなりの量のデータをインサートする場合、バルクインサートをしたほうが早いです。

例えば下記のようなデータがある場合を考えます。

$posts = new Collection();
for ( $i = 0; $i < 1000000; $i++ ) {
   /** @var Post $row */
   $post                  = new Post();
   $post->title   = 'Hello';
   $post->content = 'Good day';
}

下記のように都度save()を走らせるとかなり遅いです。

foreach($posts as $post) {
  $post->save();
}

DB::insert() メソッドを使うとバルクインサート(一括インサート)となるため早いです。

Post::insert($posts->toArray());

下記の記事を参考にするとInsert文を確認できます。
