Low latency datastore access for event-triggered functions at the edge

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.
