Currently by calling DatasourceObservation#trigger all items are refreshed with DataProvider#refreshAll. Instead of refreshing whole datasource we could enrich the API to trigger observation just for one item and use just DataProvider#refreshItem.
This would be probably enough for most actions except e.g. add/delete where we need to refresh all items.
