Batch update coordinates of hosted FeatureLayer

MichaelLodes2

Hi all,

I am looking for a solution with which I can do fast coordinate updates of FeatureLayer objects hosted on ArcGIS Online. I guess with applyEdits() function I just can update "normal" attributes, but not the geometries/graphics information. A big amount of points has to be updated programmatically everytime. (Background: application provides a csv import with 5000-10000 datasets including new point coordinates). New points also have to be created, if dataset is not existing in hosted FeatureLayer yet.

How could I do this with good performance?

Best Regards,

Michael

No that is not correct applyEdits is the way to update geometry and /or attributes for a editable layer.

I just want to push two coordinates into each dataset of an ArcGIS Online table ( = update each datasets' coordinates). If dataset with requested object id is not existing yet, a new dataset has to be created in that table. In most cases, datasets are updated and not have to be created newly

Michael,

Are you recreating each graphic or just updating the existing graphics geometry?

Thank you very much, I work with JS API 4.6, but solved it anyway. Is this an efficient way to update thousands of features or do you know a faster way?
