I agree totally, and you don’t even need an extreme example with 4.500 fields to encounter these characteristics. Just a standard extractor table from SAP CO ledger has more than 100 fields, and is an example for these thoughts. Indeed we have the distinction into “important” dimensions with hierarchies and so on (and there we use surrogate keys), typically shared with other fact tables, then “small” dimensions built by select distinct, and just pure attributes that are just staying in the fact tables “as they are”.
