Abstract: Edge functions at an edge location of a content delivery network (CDN) may access data from a back-end database without the need to make high-latency network calls to the back-end databases. When a client sends a query to the edge location, an edge function is triggered. The requested data may be retrieved from a read-only local table at the edge location (populated from a back-end database) and the retrieved data is provided to the edge function's memory for low-latency access during function execution.

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.
