13 * On-disk Log Format definitions.
15 * This file contains all the on-disk format definitions used within the log. It
16 * includes the physical log structure itself, as well as all the log item
17 * format structures that are written into the log and intepreted by log
18 * recovery. We start with the physical log format definitions, and then work
19 * through all the log items definitions and everything they encode into the
20 * log.
