Log file rotation is not solely about technical issues with the files themselves. It also addresses operational considerations such as: 1. Facilitating incremental backups of logs, which is crucial for transaction logs. 2. Minimizing the risk of losing logged events, especially during a hard system crash when open files are vulnerable. 3. Ensuring secure archival of log files to prevent tampering, or passing them to a SIEM system for threat detection. Although handling large files is less problematic today, frequently reopened large files can still negatively impact these operational needs. If you are only logging debugging information, these constraints might not apply. However, for a long-lived, large-scale system, especially one using binary logs, the question is not if you will encounter byte corruption, but when.
