Abstract: The described technology is directed towards efficiently invalidating cached data (e.g., expired data) in a hash-mapped cache, e.g., on a timed basis. As a result, data is able returned from the cache without checking for whether that data is expired, (if desired and acceptable), because if expired, the data is only briefly expired since the last invalidation run. To this end, a data structure such as a linked list is maintained to track information representative of hash-mapped cache locations of a hash-mapped cache, in which the information tracks a sequential order of entering data into each hash-mapped cache location. An invalidation run is performed on part of the hash mapped cache, including using the tracking information to invalidate a sequence of one or more cache locations, e.g., only the sequence of those locations that contain expired data.

Abstract: The described technology is generally directed towards batching two or more data requests into a batch request that is sent to a data-providing entity such as a client data access layer coupled to a data service. Described is maintaining a mapping of the requests to requesting entities so that the responses to a batched request, which may be separately streamed, may be assembled into a batch response to the requesting entity. Also described is multiplexing a plurality of requests for the same data item into a single request, which may be added to a batch request, and de-multiplexing the single response into separate responses to each requesting entity.

Abstract: The described technology is generally directed towards combining (multiplexing) two or more pending data requests for the same data item into a single request that is sent to a data providing entity such as a back-end data service. Described is maintaining a mapping of the requests to requesting entities so that a single response to a multiplexed request having data for a requested data item may be re-associated (de-multiplexed) to each requesting entity that requested that data item. Also described is batching a plurality of requests, which may include one or more multiplexed requests, into a batch request sent to a data providing entity.

Abstract: The described technology is directed towards returning less data than is available for a data item in response to a request to a data service. A virtual graph node is returned in response to client requests, in which the virtual node comprises a relatively lightweight set of information relative to the full set of information for the data item, e.g., maintained in a main (graph) node. A requesting client indicates that a virtual node is desired, and receives a response comprising the virtual node, generally processed from the main node's data into a reduced subset of the main node. The main node may be cached at the data service, and returned if and when requested.

Abstract: The described technology is directed towards obtaining and returning time offset data instead of current data in response to a data request. The time offset data may be limited to privileged clients only, and only provided thereto when desired, using a time offset value set by the client, for example. For example, a privileged user may request time offset data corresponding to a future time so as to preview how the data may be presented at a future time. Time offset data may be used by a system entity to fill a cache, e.g., as secondary cached data that may be used once primary cached data expires.

Abstract: The described technology is directed towards locating and using a template for processing data item data from a general form into a client-specific form for returning in response to a client request. A client request includes a data item identifier and client-specific information. The data item's identifier is processed into a data type and/or identifier, e.g., a string. The client-specific information is used to determine a device class, device type and/or client platform software version. The template is found in a hierarchy of templates based upon the client-specific information and the data type or data ID string, e.g., the client-specific information may be used to determine a subset of template folders that is evaluated to find a file with a filename matching the string. The folders may be ordered from most-specific to least-specific, so as to locate the most specific template file that applies.

Abstract: The described technology is directed towards maintaining and using a version-based hierarchy of software resources (e.g., file system files) to return version-specific responses to clients. A client sends its version information with each data request, and gets back a response based upon that version. Version changes are made by maintaining the current version of each software code resource and overriding the current version with a previous version for clients as needed. The technology allows updates (e.g., for new devices and new software resource versions) to be supported by inserting resources into the resource hierarchy and moving resources therein based upon versioning. A system based on deltas is also contemplated, in which only parts of a file may be changed relative to a different version, instead of overriding the entire file.
