Talk:Tournesol main database

It consists of a list of tuples of the form < update_id, contributor, video_1, video_2, order, quality_criterion, confidence, old_value, new_value, submitted, context, duration_ms, timestamp >.

Why do we need to store both the old and the new value? --Sergei (talk) 18:24, 24 February 2021 (UTC)

Yes I actually, the old value does not help much. It might help in case of concurrency issues? But this should not be a problem for "regular" contributors. --Le_Science4All (talk) 20:26, 24 February 2021 (UTC)
