To date, when I have maintained hosted feature layers in ArcGIS Online or Enterprise, I have frequently used a change detection approach and written the delta transaction.  This can result in some minutes during which the service is in flux,especially if the service is large and takes time to read into however many ChangeDetector transformers are needed.  It is also possible some writes fail.

In a webinar I watched today, the presenter demonstrated a workflow that wraps functionality available to swap the layer source for a hosted feature layer view.  This has a managerial advantage in that a candidate replacement set of data can be curated and tested alongside the production data, and a performance advantage in that swapping a layer service view’s source is faster than any other transaction approach.

As the ArcGISOnlineConnector uses the administrative ArcGIS REST API under the covers I propose a new Action for the transformer:  “View Source Swap” that lets you pick the target view and replacement service, checks the requirements are met then does the swap.
