Abstract: A data-fetching and data-rendering system may, in response to receiving a page display request, construct a static, possibly nested query for retrieving all the data to be rendered for the page and store the query result in a data store. For a future page display request, the system may similarly construct a query and determine whether the query can be resolved from the data store. If not, the system may construct a “diff query” to fetch only the missing data. In some embodiments, in response to a subsequent page update request, the system may retrieve from the server all the data likely to be viewed or updated and render the data changes corresponding to the requested update. The system may then submit the data changes to the server and undo the rendering of the data changes when the server fails to process the data changes.

Abstract: Embodiments are disclosed for fast data fetching and rendering. In some embodiments, in response to receiving a page display request, a system constructs a static, possibly nested query for retrieving all the data to be rendered for the page and stores the query result in a data store. For a future page display request, the system similarly constructs a query and determines whether the query can be resolved from the data store. If not, the system constructs a “diff query” to fetch only the missing data. In some embodiments, in response to a subsequent page update request, the system retrieves from the server all the data likely to be viewed or updated and renders the data changes corresponding to the requested update. The system then submits the data changes to the server and undoes the rendering of the data changes when the server fails to process the data changes.

Abstract: Systems, methods, and non-transitory computer-readable media can generate subscription information associated with a user and a content item, wherein the subscription information is indicative of the user viewing the content item. The subscription information is stored at a first data center. A determination is made to replicate the subscription information based on replication criteria. The subscription information is replicated to one or more additional data centers based on the making the determination to replicate the subscription information.
