caching-type Web application architecture:
A cache layer is added between the web layer and DB layer, the main purpose is to reduce the load of database reading and improve the speed of data reading. Cache access is the medium of memory, you can consider the use of distributed cache layer, so it is easier to break the limits of memory capacity, while increasing flexibility.
Second, the realization of the M
