Question

我们已经在我们的Rails应用程序中安装了Merit。它在开发环境中完美运行。由于我们开始使用Heroku（1月1日），因此我们的应用程序运行速度非常慢（对于简单的请求，响应时间为20秒），并且发现Merit会创建大量（数千个）记录。另外，当我们使用Heroku Scheduler（每10分钟运行一次）中的rake任务刷新等级规则时，它每秒发送1万个请求。

我们试图找出问题所在，并删除了我们的rake任务。现在，我们无法更新排名规则，并没有完整的绩效记录数据库：

窗扇：214045条记录

merit_scores：214 059条记录

我们的任务（使用Heroku Scheduler每10分钟运行一次）：

task cron: :environment do
  Merit::RankRules.new.check_rank_rules
end

请参阅问题末尾的日志摘录。

问题：

如何在不调用大量资源的情况下刷新RankRules？
我们如何删除所有“垃圾邮件”功绩记录，但保留会员的“良好”记录？

非常感谢

为什么Merit gem使用rake作业创建无限的记录和请求？
