PHP와 swoole은 어떻게 효율적인 데이터 마이그레이션 및 동기화를 달성합니까?

<?php

use SwooleCoroutine;

function migrate($sourceDb, $targetDb, $table) {
    // 从源数据库中查询数据
    $result = $sourceDb->query("SELECT * FROM {$table}");

    // 将查询结果插入目标数据库
    foreach ($result as $row) {
        $targetDb->query("INSERT INTO {$table} VALUES ({$row['id']}, '{$row['name']}')");
    }
}

Coun(function () {
    $sourceDb = new SwooleCoroutineMySQL();
    $targetDb = new SwooleCoroutineMySQL();

    // 连接到源数据库
    $sourceDb->connect([
        'host' => '127.0.0.1',
        'port' => 3306,
        'user' => 'root',
        'password' => 'password',
        'database' => 'source_db',
    ]);

    // 连接到目标数据库
    $targetDb->connect([
        'host' => '127.0.0.1',
        'port' => 3306,
        'user' => 'root',
        'password' => 'password',
        'database' => 'target_db',
    ]);

    // 创建协程任务，实现数据迁移
    Coroutine::create(function () use ($sourceDb, $targetDb) {
        migrate($sourceDb, $targetDb, 'table1');
    });

    Coroutine::create(function () use ($sourceDb, $targetDb) {
        migrate($sourceDb, $targetDb, 'table2');
    });

    // 等待所有协程任务结束
    Coroutine::waitForPending();
});
