Abstract
A database management system may utilize a log-structured storage system instead of a conventional storage system. The log-structured storage system may store a baseline of an object and a series of log entries describing changes to the object. At various positions in the log, a combined record may be written to contain a description of a change to the object and a copy of the corresponding version of the object. Combined records may be used to employ alternative strategies for constructing or transmitting a version of an object. Embodiments may employ these alternative strategies for replication and data caches.
