By default there will be no name for the cache in lookup transformation.  Everytime you run the session, the cache will be rebuilt.  If you give a name to it, it is called Persistent Cache.  In this case, the first time you run the session, the cache will be build and the same cache is used for any no. of runs.  This means the cache doesn't have any changes reflected to it even if the lookup source is changed.  You can rebuilt it again by deleting the cache
