Support Statistics for data that is published from query layer

Idea created by vgipiskishnit-baltic-lt-esridist Employee on Jan 25, 2013
    ArcGIS REST API allows to perform statistical functions on the Map service layers.
    Layer resource contains supportsStatistics that indicates if the layer supports statistical functions in query operations and supportsAdvancedQueries to indicate if the layer supports orderBy in a query operation.

    Awfully this functionality is limited to layers whose source is Geodatabase. I would like query layers to get this functionality as well. Query layers have huge advantage, when server side joins, computed colums are required.
