we have an existing cube where a few of the dimension tables are quite big compared to size of fact table. we understand enough about getting the correct dimension table sizes, our question revolves around the existing cube.
meaning, when we make the dimension table changes in dev and transport to val, will the transport be successful with data in the cube (so it will be stored in a format of old dimension table structure)? do we have to dump the cube before transport and then reload after transport successful?
thanks so much!
