The features are requested from the server as they are needed, in response to user or developer interaction with the layer (pan, zoom). Features are cached in the local table for the duration of the session. Queries are executed on the local cache or (if requested features are not resident in the cache) on the server. This mode is the default. In this mode, features have a minimum set of attributes, and feature geometries have no m-values even if m-values are defined by the service. This is an optimization for faster rendering. To access all attributes or access geometries that contain m-values, the features you get from a query must be loaded. You can load them yourself or request that the query method return them already loaded (see QueryFeatureFields.LoadAll). For more information, see the class description for ServiceFeatureTable.
