Invalidating query cache entries table replication

Since Commerce uses the dynamic cache service of Web Sphere, the following are examples of the types of cache:- This is where the execution of server side commands are cached.It takes the execute method of a command and determines whether it can be cached or if exist.

Invalidating cache is an extremely important activity for any Commerce site to ensure the freshness and consistency of the content being delivered to the customers.

Since the invalidation occurs before the method is executed, there is a possibility that another call can be made to get the data after it has been invalidated but before the command writes the change to the database.

Therefore it would pull the old data(stale) and since the object is no longer cached, it will write it to the cache.

It then compares the generated invalidation id to the cached objects dependency ids. Now, if we have a cached object with a dependency-id of store Id:catalog Id (1002), when the command is called and the invalidation id is created, it would look something like Category Display:store Id:catalog Id:1002 (where 1001 is store Id and 1002 is the catalog Id).

Since the dependency id matches the invalidation id, the object will be invalidated from cache.

One of the common areas that tend to cause a large number of problems is Cache Invalidation.
