Swoole和Workerman对PHP与MySQL的数据分片和分区查询的优化方法

<?php
use SwooleCoroutine as co;
use WorkermanMySQLConnection;

// 数据分片查询
function shardQuery($sql)
{
    $results = [];
    $connections = [
        new Connection('host1', 'user', 'passWord', 'database'),
        new Connection('host2', 'user', 'password', 'database'),
        // 添加更多的数据库连接
    ];

    $coros = [];
    foreach ($connections as $connection) {
        $coros[] = co::create(function () use ($connection, $sql, &$results) {
            $result = $connection->query($sql);
            $results[] = $result;
        });
    }

    // 等待所有协程执行完毕
    co::wait($coros);

    // 合并查询结果
    $mergedResult = mergeResults($results);

    return $mergedResult;
}

// 合并查询结果
function mergeResults($results)
{
    $mergedResult = [];

    foreach ($results as $result) {
        $mergedResult = array_merge($mergedResult, $result);
    }

    return $mergedResult;
}

// 示例用法
$sql = "SELECT * FROM table WHERE id BETWEEN 1 AND 100";
$result = shardQuery($sql);
print_r($result);
?>

<?php
use SwooleCoroutine as co;
use WorkermanMySQLConnection;

// 数据分区查询
function partitionQuery($sql)
{
    $results = [];
    $connections = [
        new Connection('host1', 'user', 'password', 'database'),
        new Connection('host2', 'user', 'password', 'database'),
        // 添加更多的数据库连接
    ];

    $coros = [];
    foreach ($connections as $connection) {
        $coros[] = co::create(function () use ($connection, $sql, &$results) {
            $result = $connection->query($sql);
            $results[] = $result;
        });
    }

    // 等待所有协程执行完毕
    co::wait($coros);

    // 合并查询结果
    $mergedResult = mergeResults($results);

    return $mergedResult;
}

// 合并查询结果
function mergeResults($results)
{
    $mergedResult = [];

    foreach ($results as $result) {
        $mergedResult = array_merge($mergedResult, $result);
    }

    return $mergedResult;
}

// 示例用法
$sql = "SELECT * FROM table PARTITION (p1, p2, p3)";
$result = partitionQuery($sql);
print_r($result);
?>
