SYSTEM AND METHOD FOR IDEMPOTENT METADATA DESTAGE IN A STORAGE CLUSTER WITH DELTA LOG BASED ARCHITECTURE

摘要

A method, computer program product, and computer system for destaging, by a computing device, a metadata page that includes delta tuples from a hash-based index structure. A delta tuple indicator may be added to the hash-based index structure based upon, at least in part, destaging the metadata page. The metadata page that includes the delta tuples may be destaged from the hash-based index structure to a metadata store. Any of the delta tuples added prior to the delta tuple indicator may be ignored when destaging the metadata page.
