>From Thomas:
«
Les diff hourly et minute ont été supprimés, mais ils ont été
visiblement remplacés par une nouvelle méthode de synchronisation,
basée sur Osmosis:

 http://wiki.openstreetmap.org/wiki/Osmosis/Detailed_Usage#Replication_Tasks

Les données de différences sont apparemment dispo sur:
 http://planet.openstreetmap.org/hour-replicate/
 http://planet.openstreetmap.org/minute-replicate/

D'après ce que je comprends de
http://lists.openstreetmap.org/pipermail/osmosis-dev/2009-November/000310.html,
ce nouveau système de diff a l'air d'utiliser directement des
transactions PostgreSQL. Je suspecte que ce soit potentiellement plus
efficace que la méthode actuelle. À étudier, peut-être demander sur la
liste si il y a des compétences dans le domaine.

Looks like osmosis is promising. And, in the short term, we will HAVE to use
it.

Never looked deep enough into it, but it reveals an interesting
pipeline-based architecture, even though osm2pgsql still seems to be necesary
to update the DB (but maybe I'm missing something).

Anyway, this could be of interest for us, too:

Especially this script:
