This is not as assistant QA manager that I write this. I've been thinking for
long to this feature.
With anonymization that is mandatory after 3 months in France, such a feature,
that rebuild from scratch all associations, will mostly be useless.
The only solution I see would be to have the recommendations table being filled
incrementally : we run it every week, and deal only with issues of the week
(linked to all readings still in old_issues/issues table)
That would not be perfect (you won't connect a book issued today to a book
issued 6 months ago, as it has been anonymized), but that would be much better
than the actual behaviour.

That would also solve the speed problem noticed by you & Frédéric

Note : to avoid the DB space, the solution is to create the table with
engine=myISAM
As there are no constraints, that won't do any difference

Marking "failed QA" as the feature as it is today is unusable. Too bad, it's
something i'm dreaming of !
