[sup-devel] [Heliotrope] What exactly does reordering do? Is it still necessary?

[Michael Stapelberg]

Hi,

I just realized that I forgot to import the maildir in which I store my sent
messages. After adding them to heliotrope, do I have to reorder the index? What
exactly does it do and why is that necessary?

I’m a bit confused because commit
https://github.com/wmorgan/heliotrope/commit/f7bfda9dd83db1b9cd2a51ba2599da81fc1b87c1
talks about "reindex without --reorder".

Best regards,
Michael

PS: The real time it takes to reorder my index is about 1 hour and 30 minutes :(
