[OSM-dev] having a regularly updated OSM database?

[Ákos Maróy]

Hi,

I wonder what is the best way to have a regularly updated, up-to-date
OSM database? By regularly, I mean an update about say once a month.

Previously I experimented with osm2pgsql, but that took me 5 days to
import, and the 'update' process was on the same order of magnitude.
(this is on an i7 3.2GHz system with 12GB RAM).

Is there any way that allows for faster updates down the line?

My understanding is that the osm2pgsql import will import all metadata
as well, like changeset ids, etc. actually I only need the data itself,
but such metadata. what might also help (?) is that I don't need all map
features, but basically just natural features and a limited number of
man-made features, such as roads between cities, large roads inside
cities, city & national boundaries, railroads, railway stations, & churches.

is there an efficient way of achieving an update of such data each month
within a reasonable amount of time, say below 8 hours?
