【问题描述】:
我们刚刚运行了一个亚马逊 EC2 实例,我们已经在 ec2 实例上部署了我们的 Web 应用程序,并且应用程序是在 Laravel 5.0 框架中开发的。但是我们面临一些与性能相关的问题,需要一些建议/输入同样。基本上我们正在做的是我们有一个AWS RDS实例,我们的表结构如下:
CREATE TABLE IF NOT EXISTS `adwords_data` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`client_id` bigint(20) NOT NULL,
`date_preset` enum('YESTERDAY','LAST_7_DAYS','LAST_14_DAYS','LAST_30_DAYS','ALL_TIME','7_DAYS_PRIOR_YESTERDAY','30_DAYS_PRIOR_YESTERDAY','60_DAYS_PRIOR_YESTERDAY','90_DAYS_PRIOR_YESTERDAY') COLLATE utf8_unicode_ci NOT NULL,
`CampaignId` bigint(20) NOT NULL,
`CampaignName` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`AdgroupId` bigint(20) NOT NULL,
`AdgroupName` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`Clicks` int(11) NOT NULL,
`Impressions` int(11) NOT NULL,
`ConvertedClicks` int(11) NOT NULL,
`Conversions` int(11) NOT NULL,
`Cost` decimal(10,2) NOT NULL,
`AveragePosition` decimal(10,2) NOT NULL,
`created_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
`updated_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
PRIMARY KEY (`id`),
KEY `adwords_data_client_id_index` (`client_id`),
KEY `adwords_data_date_preset_index` (`date_preset`),
KEY `adwords_data_campaignid_index` (`CampaignId`),
KEY `adwords_data_adgroupid_index` (`AdgroupId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ;
和上面一样,我有更多的 6 个表,但字段有点不同
这是 my.cnf 的外观
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...

我们的应用程序针对不同的日期范围调用 Google Adwords API,并将返回的数据存储在 CSV 文件中。我们处理这个 CSV 文件,将数据存储在 mysql 数据库表中(大约 200,000 条记录),然后我们需要处理这 200,000记录,我们需要扫描 200 K 记录中的每一个,然后应用一些业务逻辑(那是我们的内部逻辑意味着应用一些 mysql 聚合,如 Sum、Avg 等)但是处理这 200 K 记录需要很长时间,大约 2 小时但是我们需要缩短处理时间。
下面是我们用来处理这 20 万条记录的代码库。我们使用 Laravel 的 chunk 方法来批量处理数据
https://laravel.com/docs/5.0/eloquent
\DB::table('adwords_data')->select('CampaignId', 'AdgroupId')->where('client_id', '=', $client_id)->groupBy('CampaignId', 'AdgroupId')->chunk('500', function ($adwords_data) {
foreach($adwords_data as $data){
// process each AdgroupId by checking the summation of conversion stats and apply conditions
}
}
在完成表 adwords_data 的过程后,我们对其他 6 个表重复上述过程。但性能不如我们需要更快地执行。
谁能建议我们提高性能的最佳方法?
谢谢!

您的问题缺乏足够的细节,无法让任何人提供好的建议。我不是 MySQL 专家,但你的表定义对我来说看起来不错,不是火箭科学 - 所以潜在的问题是 1)MySQL 配置(“my.cnf”)没有配置为最佳 2)你的处理代码写得不好 3)你如果您使用的是 AWS nano,可能需要更大的机器。我建议您提供 my.cnf 文件以及您的代码,这可能会增加您获得合理帮助的机会。祝你好运

@fiprojects 当然我可以为您提供!你能分享我你的电子邮件ID更多细节我会通过电子邮件向你解释

没有更多信息可以回答?我的电子邮件就是我的个人资料

Ronak - 这是一个技术论坛 - 虽然我可能会提供帮助,但我可能无法提供最佳解决方案 - 您最好在论坛中分享您的代码,以增加获得最佳解决方案的机会最好的人的帮助。

@fiprojects 我已经编辑了帖子,现在有用吗?
