   Use case :
   
   VAT declaration needs to process all invoices of a period.
   
   This can be thousands of entity tabel records,
   loading them all in memory will probably cause them to be written to disk.
   
   
   Should we batch or not ?
   If batching, can we / should we keep the BusinessEntity+DataAcess alive for faster processing of next batch ?

   "Should we batch or not ?"
   
   That really depends on size :) But probably yes.
   
   Assuming this is executed from a Business Task on the backend, successive calls to the Business Entity (via DatasetModel or any other method) should always be reusing the same instance anyway - as we're still within the same request.
