Answer / amol palekar
main difference between normal and bulk load is, in normal load Informatica repository service create logs and in bulk load log is not being created. That is the reason bulk load loads the data fast and if anything goes wrong the data can not be recovered. But in normal load since the log is created the lost data can be recovered.
