Swoole和Workerman对PHP与MySQL的数据分片和并行查询的优化方法

<?php
// 定义需要查询的大规模数据
$data = [/* ... */];

// 定义服务器列表
$servers = [
    'server1' => '127.0.0.1:9301',
    'server2' => '127.0.0.1:9302',
    'server3' => '127.0.0.1:9303',
    // ...
];

// 创建Swoole HTTP客户端
$client = new SwooleHttpClient('127.0.0.1', 9501);

// 将数据分成若干个片段
$chunks = array_chunk($data, ceil(count($data) / count($servers)));

// 定义每个片段查询的回调函数
$callback = function ($result, $chunkIndex) use ($client) {
    // 处理查询结果
    // ...

    // 继续查询下一个片段
    $client->post('/query', ['chunkIndex' => $chunkIndex + 1]);
};

// 发送第一个查询任务到第一个服务器
$client->post('/query', ['chunkIndex' => 0]);

// 处理查询结果
$client->on('response', function ($response) use ($callback) {
    $result = json_decode($response->body, true);

    // 处理查询结果
    // ...

    // 继续查询下一个片段
    $callback($result, $result['chunkIndex']);
});

// 启动Swoole事件循环
$client->close();

<?php
use WorkermanWorker;

// 定义需要查询的大规模数据
$data = [/* ... */];

// 定义服务器列表
$servers = [
    'server1' => '127.0.0.1:9301',
    'server2' => '127.0.0.1:9302',
    'server3' => '127.0.0.1:9303',
    // ...
];

// 创建Worker进程
$worker = new Worker();

// 监听查询任务
$worker->onWorkerStart = function () use ($data, $servers) {
    // 将数据分成若干个片段
    $chunks = array_chunk($data, ceil(count($data) / count($servers)));

    // 创建多个连接
    foreach ($servers as $server) {
        $connection = new WorkermanMySQLConnection($server);
        $connections[] = $connection;
    }

    // 并行执行查询任务
    foreach ($chunks as $chunkIndex => $chunk) {
        foreach ($connections as $connection) {
            $connection->query("SELECT * FROM `table` WHERE `id` IN (" . implode(',', $chunk) . ")", function ($result) use ($chunkIndex) {
                // 处理查询结果
                // ...
            });
        }
    }
};

// 启动Worker进程
Worker::runAll();
