如何使用PHP和swoole搭建高可用的大数据处理系统？

<?php

use SwooleCoroutine;
use SwooleKafkaProducer;
use SwooleKafkaConsumer;

// 配置Kafka集群
$config = [
    'metadata.broker.list' => 'kafka1:9092,kafka2:9092,kafka3:9092',
    'group.id' => 'group_id',
    'enable.auto.commit' => 'true',
    'auto.commit.interval.ms' => '100',
];

// 创建生产者
Coroutine::create(function () use ($config) {
    $producer = new Producer($config);

    // 发送一条消息到Kafka
    $producer->send([
        [
            'topic' => 'my_topic',
            'value' => 'Hello, Kafka!',
        ],
    ]);
});

// 创建消费者
Coroutine::create(function () use ($config) {
    $consumer = new Consumer($config);

    // 从Kafka订阅消息
    $consumer->subscribe(['my_topic']);

    // 持续消费消息
    while (true) {
        $messages = $consumer->consume();

        foreach ($messages as $message) {
            $topic = $message['topic'];
            $partition = $message['partition'];
            $offset = $message['offset'];
            $value = $message['value'];

            // 处理消息
            // ...
        }
    }
});

// 启动协程调度器
Coroutine::set([
    'max_coroutine' => 100000,
]);

Coroutine::start();
