ArcGIS Pro SDK - Updating the same attribute on multiple features

Question

Hello all, I am trying to update a single attribute on 100 different features of at most 4 different layers, with the same value. In my case I have 100 features that need a "comments" field updated. I used the Inspector class to modify multiple features, since it seems to be the preferred method on the ProSnippets documentation. However I noticed something odd when it took nearly 20 seconds to complete. I ran Fiddler to look at all the network calls to ArcGIS Server that were made during the process and saw that "applyEdits" was called once for each feature that I loaded into the inspector (see below screenshot, under code snippet), this resulted in 100 applyEdits calls and 100 queryFeature calls, 200 in total. I was expecting at most 1 call per layer. I recorded some timings based on larger feature counts for my EditOperation to finish the "ExecuteAsync" method. Is there a way for me to configure Inspector to only make at most 1 call per updated layer? Or is there a better method through the SDK? Feature CountDuration (in seconds)104 20210 54306 70500 109650 1131100 2471200 276 public static async void ApplyUpdateUsingInspector(IDictionary<Layer, List<FeatureObject>> layerAttributes, object value, string fieldName) { await QueuedTask.Run(async () => { var editOperation = new EditOperation(); editOperation.Name = "Changing attribute..."; editOperation.ProgressMessage = "Working..."; editOperation.ShowProgressor = true; editOperation.CancelMessage = "Operation canceled"; editOperation.ErrorMessage = "Error updating attributes"; foreach (var layer in layerAttributes.Keys) { var features = layerAttributes[layer]; var objectIds = from feature in features from attribute in feature.Attributes where attribute.Key == "ObjectID" select (long)attribute.Value; var inspector = new Inspector(); inspector.Load(layer, objectIds.ToArray()); inspector[fieldName] = value; editOperation.Modify(inspector); } if (editOperation.IsEmpty) { editOperation.Abort(); } else { await editOperation.ExecuteAsync(); } }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Kevin,

There's no plans to expose the sessionID. The focus will be on providing a mechanism to do the bulk creates/updates.

Hi Sean,

ApplyEdits from the pro-sdk will not work since it does not support Undo/Redo functionality, and the user needs to be able to undo the changes that we are attempting to make with this bulk transaction.  Also this does not support updating the map, which we also require for this process.

I tried Calculate Field from within Pro, and for only 37 features this took 2 minutes and 16 seconds.

Can you confirm if sessionId will be exposed in the public API at some point?

Hi Kevin,

The sessionID isnt exposed in the public API.

A few things to try;

ApplyEdits is available for console applications. It wasn't designed to run in Pro, but it isn't blocked from doing so either. Be aware of the caveats mentioned in that topic.

As a curve ball you can also try the GP tool, "calculate field" called via Geoprocessing.ExecuteToolAsync. This tool doesn't fire row events but im unsure how well this will perform against a branch version.
