Abstract

See full text

A technique for managing a metadata transaction log consolidates multiple mapping pointer changes that affect a single metadata block in a single transaction entry. The technique creates a data structure that identifies the mapping pointers in the metadata block that are changing, and stores the data structure in the transaction entry along with records that describe the individual mapping pointer changes.
