Whenever my code needed some sort of data-caching mechanism, I've tended to "roll my own," as the saying goes.
每当我的代码需要某种形式的数据缓存机制时，我总是倾向于“自己动手丰衣足食”这句俗语所说的那样做。
Although you can use memcached to store the rows of data as loaded from a database, this is really query caching, and most databases provide their own query-caching mechanism.
虽然可以使用memcached存储加载自数据库的数据行，但这实际上是查询缓存，并且大多数数据库都提供各自的查询缓存的机制。
