I explained how WAL guarantees reliability by logging changes before flushing them to disk, thus enhancing database performance. By logging updates in a separate file, WAL minimizes disk writes and enables point-in-time recovery. I highlighted the importance of CRC checks in protecting data integrity within the log file. WAL's structure includes segments and pages, with each entry having a unique Log Sequence Number for easy reference and recovery.
