How long is the cache appropriate?
For example, Memcache, the cache period of data does not change, such as 30 minutes, this is not good, but the cache time set small meaning is not big, such as 30 seconds, cache this thing, in the end to set how long to be good?

I don't know if that's the answer to your question, hehe.
