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).
