Please add a filter possibility when sharing featurelayers that only uploads data that corresponds to the definition query set on a layer.
Simple Usecase: Large dataset, we want only parts of it to be shared/copied to ArcGIS Online.
Important to understand: in version 3.0.2 of ArcGIS Pro, the definition query is applied on the published layer. Data is not visible but copied/shared to ArcGIS Online! The only way to "refind" the data is to delete the definition query in the admin interface of the rest service (updateDefinition Rest endpoint).
