<p>A database system may maintain a plurality of log records at a distributed storage system. Each of the plurality of log records may be associated with a respective change to a data page. A snapshot may be generated that is usable to read the data as of a state corresponding to the snapshot. Generating the snapshot may include generating metadata that is indicative of a particular log identifier of a particular one of the log records. Generating the snapshot may be performed without additional reading, copying, or writing of the data.</p>
