SMART PREFETCHING OF OPERATIONS TECHNIQUE

Abstract: a smart prefetching of operations technique prefetches metadata and/or data of objects stored in a multi-cloud snapshot technology (mst) service associated with an object store. one or more data objects (e.g., an application) at a primary site may be designated for backup or failover to a secondary site, e.g., in the event of failure of the primary site. smart prefetching logic of the mst is configured to prefetch the object metadata and/or object data from the object store to serve subsequent requests without accessing the object store. to that end, when storing data to the object store as one or more objects, mst maintains specific metadata along with the data of the objects. the technique utilizes the specific metadata to prefetch the object metadata and/or object data before receiving actual read requests for that data to improve the read latency and throughput when restoring the application as soon as possible.
