Caching data in memory can dramatically increase performance, but remember that the data is then somewhat vulnerable.

在内存中缓存数据能大大提高性能，但是数据会显得有些脆弱。

Some situations also call for caching data in memory to minimize the number of data base calls for data that does not change.

同样一些情况要求在内存中缓存数据，以此来减少并不改变的数据被数据库调用的次数。

All caching and in-memory data can be redesigned as replicated nodes based storage.

所有缓存和内存数据都可以重新设计为基于存储的复制节点。
