Hi all
I added a new feature to my osm-history-renderer/-importer that allows
you to handle much larger areas, by using the RAM more efficiently. In
theoriy it should be possible wo import a fill history planet with ~32GB
of RAM.
On my Notebook I imported rheinland-pfalz.osh.pbf (308M) with the sparse
nodestore. It took around 1.2 GB of RAM from which apparently ~700M was
taken by the nodestore and 400M by the pbf reader. Process Runtime was
around 30 Minutes. The generated Tables on disk took ~14 GB including
indexes.
In comparison, africa.osh.pbf and north-america.osh.pbf are of a similar
size and I guess one could even import netherlands.osh.pbf on a home
notebook with 4 GB of RAM. Maybe even germany.osh.pbf or france.osh.pbf
would work out with 6 GB or 8 GB. I'd love to hear feedback about this.
