Laravel插入/更新/删除

Question

I currently have this code below, however when adding around 2000 rows this runs too slow due to being in an foreach loop.

foreach($tables as $key => $table) {

    $class_name = explode("\\", get_class($table[0]));
    $class_name = end($class_name);

    $moved = 'moved_' . $class_name;
    ${$moved} = [];

    foreach($table[0]->where('website_id', $website->id)->get() as $value) {
        $value->website_id = $live_website_id;
        $value->setAppends([]);
        $table[0]::on('live')->updateOrCreate([
            'id' => $value->id,
            'website_id' => $value->website_id
        ], $value->toArray());
        ${$moved}[] = $value->id;
    }

    // Remove deleted rows
    if ($table[1]) {
        $table[0]::on('live')->where([ 'website_id' => $live_website_id ])
            ->whereNotIn('id', ${$moved})
            ->delete();
    }
}

What is happening is basically users will add/update/delete data in a development server, then when they hit a button this data needs to be pushed into the live table, retaining the ID's as auto incremental id's on the live won't work due to look-up tables and multiple users launching data live at the same time.

What is the best way to do this? Should I simply remove all the data in that table (there is a unique identifier for chunks of data) and then just insert?

I think can do:

• You can create a temp table and fill just like your development server and just rename table to published table
• Use Job and background service(async queue)
• You can set your db connection as singleton, because connecting multiple times can waste time
• Can use some sql tools for example if use postgresql you can use Foreign Data Wrapper(fdw) to connect db to each other and update and create in a faster way!
