A digital image representation may be created by a distributed platform system for a site based on each of the plurality of user-specific actions. The digital image representation may be created by determining a current state of the site from one or more application components of the site, computing a desired state for the site to reach from the current state at some point in time, and creating the digital image representation for the site using the computed desired state to be reached by the site at some point in time. The distributed platform system uses one or more digital models for creating the digital image representation for the site. The distributed platform system may be configured to update the site to reach the desired state based on the digital image representation of the site, at some point in time.

Method and system for generating desired states for edge sites

In one embodiment, a method may use one or more Representational State Transfer (REST) Application Programming Interfaces (APIs) to receive data associated with a web application from a first user interface (UI) client device. The method may use the one or more REST APIs to determine a stateless operation by performing stateless pre-processing on the data associated with the web application and one or more contextual features associated with the stateless operation. The method may determine an augmented notification by applying an augmentation operation on the one or more contextual features and the stateless operation. The method may determine a stateful operation using the augmented notification. The method may receive a request for an update on the data associated with the web application from a second UI client device. In response to receiving the request, the method may communicate the stateful operation to the second UI client device.

High scalability and end-to-end consistency for web applications in distributed environments

A method for unjoining and rejoining clusters of computing nodes in edge site computing networks to reduce the impact of interruption to connectivity between computing nodes is presented. The method includes accessing a cluster of computing nodes executing on an edge site computing network. The cluster of computing nodes includes a plurality of follower computing nodes and a leader computing node. The method further includes detecting an interruption to connectivity established between the leader computing node and one or more of the plurality of follower computing nodes. In response to detecting the interruption to connectivity, the method includes bifurcating the cluster of computing nodes into a first subcluster of computing nodes and a second subcluster of computing nodes. In response to detecting a restoration of connectivity, the method includes recombining the first subcluster of computing nodes and the second subcluster of computing nodes.

Unjoining and rejoining clusters in computing networks

In one embodiment, a data sharing platform performs a series of data operations to provide different types of data via different sharing services of the data sharing platform that are derived from data shared by a particular data owner. The data sharing platform generates tag data associated with the particular data owner for one or more of the series of data operations. The data sharing platform determines, based on the tag data, an attribution chain that links the data shared by the particular data owner to the different types of data provided via the different sharing services. The data sharing platform sends an indication of the attribution chain for display.

Attribution of user data sources across datasets in a data sharing platform

In one embodiment, a device receives, from a requestor, a query function that queries a dataset and an intended use schema associated with the query function. The device determines, using a policy ruleset, whether the intended use schema falls within an available schema for the dataset. The device executes the query function on the dataset to form a result data, when the intended use schema falls within the available schema for the dataset. The device provides the result data to the requestor.

Data leakage avoidance in a data sharing platform

In one embodiment of the present invention, a method implemented on a computing device includes: retrieving a set of channel parameters, the set of channel parameters defining a television channel schedule made of a plurality of viewing time periods; retrieving a set of regional parameters relevant to a geographical area, the set of regional parameters defining at least one regional viewing time period of a first duration; identifying a viewing time period from the plurality of viewing time periods relevant to the at least one regional viewing time period by comparing the regional parameters to the channel parameters; retrieving an abstract schedule associated with the identified viewing time period, where the abstract schedule is a pro forma schedule of programs having a second duration and comprising a set of program content items; and generating a concrete television schedule for the at least one regional viewing time period, where the concrete television schedule is a an instantiated finalized schedule produced by mapping the second duration to the first duration and rearranging the set of program content items of the retrieved abstract schedule.
