May I ask you where you got this dump from? It's not an official one, is it?

Yes, it is! It may be the only way to get some historic information needed, to eg. show a changeset in some kind of cool diff-view or to develop smart changeset-revert tools (see [1] and [2] for this problem, the OSM-API does not and will in the near future not provide this kind of information). > However, only Ptolemy (currently WMF production server) has disk space > available for the whole API database; I do not see - but I might be wrong > - currently use for this database (except for genering mapnik DB out of it) > - for the WMF production environment. I do not see either. If Ptolemy won't be accessible by cassini and it's only task will be serving the mapnik render with gis-data, then I don't think we'll that much HD-Space on it. I'm unsure about the remaining system configuration (e.g. ptolemy has 8GB more RAM). > So we might have add disk space to Cassini to have space for the full API > database, and start importing it there.

I don't think there are too many *live* tools on cassini (although there may be some in development stage). > We might alternatively give up on full database API altogether > and just run Mapnik DB on the Ptolemy as we have. The simple question is: do we want tools that can play with the history of osm-objects or not. If we want, we'll have to supply the necessary data.
