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 generally directed towards coordinating the generation, validation and enabling of content selection graphs in an in-memory content selection graph data store. When a set of content selection graphs is requested, a coordinator starts the generation of the relevant graphs. Upon successful generation, the coordinator starts a validation of the generated graphs against rules for the nodes/response data in the graphs. If the generated graphs pass validation, the coordinator enables the graph set for use in an in-memory cache, whereby when a request to return content selection data is received, an active graph that corresponds to the request and the current time is accessed to obtain and return the response data as the requested content selection data.

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.

Abstract: The described technology is generally directed towards validating content selection graphs for use in an in-memory content selection graph data store. When a content selection graph data is generated, the graph nodes can correspond to prebuilt response data. The response data for any of the nodes can be verified against rules based on the type of a node, for example, as well as based on client-specific information for types of clients. The overall validation process can validate the content selection graph for subsequent use, can result in errors or warnings being logged (which may or may not render the graph unusable, e.g., depending on severity), or can fail the content selection graph. If validated, the content selection graph can be used to rapidly return response data when content from the graph is requested.

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 a data transformation pipeline architecture of a data service that processes generalized datasets into datasets (e.g., video data or graph nodes) customized for a particular client device. Described herein is maintaining a set of data transformation models at a data service, and upon receiving a client request for data, selecting a relevant subset of the transformation models and arranging the subset into a data transformation pipeline. In general, the pipeline of transformation models transforms the generalized data into the format and shape that each client device expects. The subset may be selected based upon device type, device class and/or software version information (and possibly state data) sent with each data request. The transformation models may be maintained in a hierarchical data store such as files in a file system to facilitate retrieval by searching the hierarchy for appropriate transformation models.

Abstract: The described technology is directed towards a cache framework that accesses a tier of ordered caches, in tier order, to satisfy requests for data. The cache framework may be implemented at a front-end service level server, and/or a back end service level server, or both. The cache framework handles read-through and write-through operations, including handling batch requests for multiple data items. The cache framework also facilitates dynamically changing the tier structure, e.g., for adding, removing, replacing and/or reordering caches in the tier, e.g., by re-declaring a data structure such as an array that identifies the tiered cache configuration.

Abstract: The described technology is directed towards having user interface objects rendered on a client device based upon provider data of at least part of a client provider graph. The client provider graph comprises a plurality of providers (graph nodes), in which each provider has provider data corresponding to user interface object data. The data of one provider has a reference set containing one or more references (e.g., edges) that each identify another provider, thus forming the graph. Client requests for other provider data are made based upon the reference set. The other provider data is received in response to the client requests, and is maintained at the client (e.g., in a client cache) to build the client graph.

Abstract: The described technology is directed towards repurposing expired cached data when no unexpired data is available. Cached, unexpired data is used in response to a request when such data exists. If such data does not exist, e.g., at a front-end data service, then an attempt to obtain the requested data from another (e.g., back-end data service) is made. If the attempt is unsuccessful, and expired cached data exists, the expired cached data is returned in response to the request, e.g., instead of returning an error. A back-end data service may similarly return expired cached data when the back-end data service is unable to obtain unexpired requested data elsewhere. An emergency mode may be entered in which data, whether expired or not, is returned from a cache when such data exists, such as when an attempt to obtain the data elsewhere is known in advance to be futile.
