I have an application in which I load data from the database without almost any transformation and then store the tables in qvd files.
I don't have any date fields like "creating data" or "modification date". I was wondering if there was any tips to use kind of incremental load ?
Can I compare the values to the ones existing in the qvd and then add only the new lines ? But if I have to compare each record of the table to each record of the QVD, would that improve the performance ?
Thank you for your anwers
