很好，缓存数据避免了并发操作的可能性，但这没有帮助，因为从数据库缓存数据意味着如果数据发生更改，则缓存已过期.它所做的只是减少数据库操作的成本，而代价恰恰是您可能会显示过时的数据.

Well, caching data avoids the possibility of concurrent actions, but this is not helpful, because, caching data from your DB means that your cache goes out of date if the data changes. All it does do, is decrease the cost of database operations, the penalty is precisely that you could be showing data that is out of date.

我很高兴知道这意味着什么.您可以编辑您的帖子以进行澄清吗?还是后半部分意味着这意味着一个谜?

I am intrigued to know what this means. Could you edit your post to clarify ? Or does the second half mean that this is meant to be a riddle ?
