How you choose to handle caching is often based on the type of data that you are caching and how that data is used.
高速缓存连接通过避免与数据库连接的时间(除了第一次)减少了设置时间。
Caching the connection reduces the setup time by avoiding the time to connect to the database (except for the first time).
这是一个键值，如同数据库里的键结构，唯一地标识每一个高速缓存条目。
This is a key, similar to a database key structure that identifies a particular cache entry as unique.
获得当前时间的网络调用是高速缓存的一个完美项，因为您的10秒约束意味着数据在至多10秒钟之内不会更改。
The network call to get the current time is a perfect item to cache because your 10-second constraint means the data will not be changing for, at most, 10 seconds.
如果您熟悉高速缓存，从本质上来说会话与它是相同的概念—存储数据以减少响应时间和服务器工作负载。
If you're familiar with caching, it is essentially the same concept — storing data to reduce both response time and server workload.
