 Description  « Hide
See NUCRDBMS-594 where we added bulk fetching for collection (Set/List) fields. Could do the same for Maps in principle. Note that the load of a Map currently involves more than 1 SQL (see SCOUtils.populateMapDelegateWithStoreData) so this process may need revising before attempting a bulk fetch
