Storm does do serialization in local mode just like in cluster mode, but you have to understand that storm only serializes objects when necessary. If the object is sent within a worker it is not serialized. One of the requirements of storm is that you treat your input as immutable and you don't modify your output once it is sent. This is because that same object may be in use by another bolt also.
