10 years agoDoes updating data process download all data from the source again
Power BI service updates the data of the model in a regular basis (for example once a day). Does it download the whole data everytime again and deletes the current one or does it use some kind of a differential process (just downloading the new and modified data)?
MbProg I guess you're referrign to data refresh in power bi service. if yes then data refresh in power bi service is not delta ie every time it refreshes it takes all the data from source and replace it with existing data in the model.
