Yeah and why not akonadi and then mysql, which it uses.

Akonadi is the reason why I wish so much to switch again from kmail to 
gnus, because it takes 100% of the cpu all the time, and yet makes kmail 
slows and extreeemely buggy most of the time (loosing mail, hanging 
forever to open some mails, some mails gets unreadable and undeletable, 
etc.).  The database is mostly corrupted but since it’s complex I have no 
fucking idea of how to fix it.  The only “database” I’m understanding 
anything to, here, is the list of mail, which is a bunch of recursive 
maildirs… but apparently these are not enough, and I regularely find myself 
to delete all akonadi data and loose a lot of metadata, thinking that I 
may one day reimport all the maildirs into gnus, and regenerate a lot of 
nov databases during one long day…

…but I still don’t switch, because the way kmail stores mail is of course 
at least partially incompatible with gnus, because all these databases are 
so complex…

And I think that a fear of getting a such thing into emacs, under the 
excuse that “for the developer, it works” and that “it brings more 
features” is what makes people afraid from something even as minimal as 
sqlite… for emacs is one of the very few software to be minimal and 
transparent enough to have a better situation than sqlite
