HI rishi007bansod, The difference is that the main focus of StreamTransformer is updating data in a stream cache based on its previous value without a need to refer to the cache directly: you are just operating on a received MutableEntry. StreamVisitor, in turn, is a more general-purpose tool for entries manipulation. It won't update cache entry without explicit call to cache.put().
