How do you use this cache system? if every function is used, you must first determine whether there is any cache in memcache. if there is any cache, will it be written to memcached first?
The code is:
If (! Memcache ){
Write data to memcached
} Else {
Get data directly from memcached
}

The problem is, if every function and module is used to judge memcached, will it be very troublesome? is there any good architecture method? Share:

So Far

This is actually just a few things.

If you need to use this in many places, you can encapsulate the storage, query, and cache of the database. each time you directly call the encapsulated method, you do not need to write the get and set of memcache every time.
------ Solution --------------------
The principle of using cache (no matter what kind of cache) is:
Write the cache only when data is generated different from the cached data. Such as database insertion and modification
Read-only in other places
