    Abstract: A datastore engine at an edge location of a content delivery network (CDN) may perform low-latency query processing and data retrieval for multiple types of databases at one or more origin servers. When a client sends a query to the edge location, the datastore engine translates the query from a back-end database format into a native format of the local edge datastore. If the requested data is not there, then the datastore engine retrieves the data from the back-end table and inserted inserts the data into the local edge datastore. By using multiple queries over time to re-construct data from the backend database tables at the edge, the datastore engine may provide low-latency access to data from the backend database tables (avoiding the need to retrieve data from the back-end tables to serve subsequent queries).

    Abstract: Techniques for stateful computing at the edge of a content delivery network are described. In some embodiments, a point of presence of the content delivery network includes proxy servers, function execution units, and function state cache servers executing on computer systems within the point of presence. A proxy server checks for requests for resources hosted on behalf of customers of the content delivery network that trigger a customer-specified function. When a function is triggered, the proxy server selects an execution unit and sends a function execution request to the execution unit. The execution unit executes functions of many different customers of the provider network. Upon receiving a request to execute a function that is stateful, the execution unit retrieves the function state from a function state cache server, execute the function, and returns a result to the proxy server.

    Abstract: Various embodiments of apparatuses and methods for transaction processing at edge servers in a content distribution network (“CDN”) are described. In some embodiments, an edge server receives an initial request from a client for content associated with a particular origin, and then provides the content to the client. The edge server can then receive another request from the client that might include an indicator for transaction processing. The edge server determines that transaction processing is indicated for handling this new request, in some embodiments. The edge server can then send a transaction notification to the origin, receive a transaction continuation response from the origin, and then execute a data transaction with transaction entities that are distinct from the content distribution network and the origin, in some embodiments. If the transaction is successful, the edge server can notify the client and the origin of the successful transaction, in some embodiments.

    Abstract: A content delivery network (“CDN”) is provided herein that predicts content resources (e.g., a data object, such as a video file, an audio file, a script, an image, a document, etc.) that may be requested by a user device in the future and transmits or pushes such resources to the user device prior to receiving a request. The CDN may use artificial intelligence models, such as Markov models, in order to predict which content resources to retrieve and transmit proactively to the user device. The predictive techniques implemented by the CDN may reduce a latency of delivering requested content resources and/or a latency of the user device in rendering and displaying a content page.

    Abstract: Techniques for using a satellite as a part of a content delivery network are described. For example, in some instances a satellite is to receive a request for a resource hosted by the content delivery network, determine that the request for the resource cannot be served by the satellite, determine a first entity to ask for the resource, send a secondary request for the resource to the determined first entity, receive the resource from the determined first entity, respond, to a user of the content delivery network, to the request using the received resource for the resource, and respond to a subsequent request using the cached received resource.
