[development] Avoid caching of specific fields in table cache_fields?

Hi, Does anyone know if there's a way to avoid having fields cached in the database table cache_fields (Drupal 7)? This would have to be enforced from within the module that defines the field, regardless of which entity the field is attached to.. After digging in the code I suppose it's just not possible, but if you have any pointers, let me know! Sven
