This is a feature which people have been asking about for a long time. It's finally here in 3.0.5. When configured with "track = yes", the detail file reader will track its progress through the detail file. When it has successfully read and processed an entry from the file, that entry is marked as "done". That means if the server is restarted, it will quickly scan through the detail file, and ignore the records marked "done". It will then continue processing the next (unfinished) entry. This change means that detail file entries will be processed once, and only once. It also means that the server will make progress through the detail files much more quickly when it's restarted.
