Create REST methods for bulk object retrieval
For reporting purposes we would like to have REST methods to retrieve metadata about objects in bulk. Right now we have to retrieve the list of objects first, then get metadata about each of them. This is definitely a very inefficient way to build reports. Essentially, would like a REST method that allows to query for the following objects AND specify fields we want to see in the query results, such as created and last modified dates, author, number of items (in a list), size, permissions, etc. We believe that having such REST methods for Sites, Lists and libraries, and List items and documents can make reporting more efficient, considerably enhance solution performance, and minimize unnecessary load on SharePoint.
For creating dashboards, we have a new product feature called Microsoft Graph data connect. This currently is In Preview and supports entities such as mail, calendar, contacts, users. In future it will support other entities available on the graph. You can read more about data connect here https://developer.microsoft.com/en-us/graph/blogs/microsoft-graph-ignite-2018/ ^JT
