Redis pipeline 在连续一万次插入操作测试中的使用

Redis pipeline 在连续一万次插入操作测试中的使用中
如下代码运行后的结果是

  10000noPipeline:0.36595296859741s
  10000yesPipeline:0.016739130020142s
 

可以看出pipeline确实可以节省很多时间

connect("127.0.0.1");
    $redis->flushAll();

    $start_time = microtime(true);

    noPipeline($redis);
    $end_time = microtime(true);

    echo "noPipeline:".($end_time - $start_time)."s\n";

    $redis->flushAll();
    $start_time = microtime(true);

    yesPipeline($redis);
    $end_time = microtime(true);

    echo "yesPipeline:".($end_time - $start_time)."s\n";;


}

function noPipeline(Redis $redis)
{
    $i = 0;
    while ($i < 10000) {
        $redis->incr("x");
        $i++;
    }
    echo $redis->get("x");
}

function yesPipeline(Redis $redis)
{
    $pipe = $redis->multi(Redis::PIPELINE);
    $i = 0;
    while ($i < 10000) {
        $pipe->incr("x");
        $i++;
    }
    $pipe->exec();
    echo $redis->get("x");
}

main();
