- Ok, let's have a counter example. Supposing files are sorted by creation
- date/time (as would apparently be the case with your technique). Suppose
- there were no new articles, and one was expired. The users' join files
- are now out of sync:
-
- Before unbatching : 1, 2, 3, 4, 5
- After unbatching : 1, 2, 3, 4

- Suppose there was one new article, and one was expired. No change to the
- users' join files, but it now points one too high:
-
- Before unbatching : 1, 2, 3, 4, 5
- After unbatching : 1, 2, 3, 4, 5

- Too simple, maybe? I think I'll just avoid re-sequencing my articles.
- How does re-sequencing enhance the general operation of Waffle?
