I am looking for a way of appending new data to an existing feature service instead of overwriting it every time. The existing feature service holds attachments and becomes quite big over the time. Our internet here in Rwanda is sometimes not very stable so we are looking for a way to avoid uploading a GB of data every time the data is updated.
(By the way: Is there a way to see the size of a feature service including the attachments?) While locally I can append new data to an existing feature class I haven't seen this option yet for feature services. Would it maybe be possible to do this through a python script? I would be happy if you have any suggestions.
