New Activities Called "Compared Feature" and "Compared Feature Sets"

It will be handy if we can have activities easily compare two features, for example to show me what attributes have been updated.

For comparing feature sets, it can be what are new records being added/removed/updated.

Just an idea :)

  Then you should post it here

  What should be the result of these activities?

  I see the value there, but that sounds a little processor intense for a web client to me. 

  FME Workbench, or Feature Compare in ArcGIS Pro, are both desktop applications which don't need to concern themselves with how long a task takes to complete so they can sit there and chew through data for days in a row when they must.  Browser-based apps like VS Web need to handle concerns like user engagement and application timeout. 

  Further, they don't have access to the kind of compute available to a desktop app, so these kinds of operations are going to take even longer than they do in a desktop environment.  If you can write a web client utility that can do this in a browser, then please do because it would be very cool to have, but I don't know of any JS function that does this.  If you need that functionality exposed, I know that you can go with Esri and publish a geoprocessor that exposes Feature Compare.  You may need to figure out how you're going to handle a long-running process though; a solution to that might be having the user supply an email address with their submission or you can write your app to check in with the geoprocessor every minute until its done.

  If you have a more specific question about how you might compare two datasets, there is a lot of that going on in Workflow and maybe someone in this community can help you out 😁.  Activities like Get Feature Attribute Values and Compare Geometries can be very helpful in looking for differences between two data sets when combined with activities like For Each loops.
