Detailed Description

Format of log records.

The fields are carefully defined to allow them to be aligned and sized the same on sparc & intel architectures. Each log record has a common structure at the beginning.

The log record on disk (lrc_seq) holds the sequence number of all log records which is used to ensure we don't replay the same record.
