A multi-server cache dependency Solution

System design: The system is divided into multiple small systems, each of which is deployed on different servers and provides uniform WebServices for small system calls, WebServices and Database Communications.

Problem:

When cache is used by each system, when a system modifies the cached content, other system caches cannot receive notifications for synchronization and cache dependencies (files and databases cannot cross-WebServices dependency)

Solution:

1. Add a cache Id field to the database

2. Read the cache ID to each system.

3. If you modify the cache, modify the cache ID.

4. Each time the system accesses WebServices, the system reads the cache identifier. If this parameter changes, it reloads the cache.
