From what i gathered from our conversation earlier, XAPI's index is too large for Cassini. It would have to go on the main server. I propose to talk to Sven and Jens about it. Or what do you mean by "a mirror of the API"?
XAPI is a replication of the main OSM database that is maintained to be current within about 30 minutes of the real OSM database. It exposes the data through a similar API to the real OSM database. It requires about 300Gb of disk.
There was a point made earlier that there wouldn't be space for XAPI because that would leave no room for the replicated database. Now it seems questionable whether there's a real need for an additional replicated database on osm-ts. What role would it play, what applications would use it?

Is there a list of proposed applications? The only one I know of is query-to-map.

Maybe:) This is the current space the DB is taking @ OSM: http://pastebin.com/f39a15e34 Maybe a Planet.osm import is smaller than that though. I could check and see if it fails. I was under the impression that replication was planned so that users on the osm-ts would have access to the DB without hammering the main DB (which would be there for production tools) with expensive
queries.
Or so I gathered from our talk on IRC on the toolserver channel, but may have misunderstood you. _______________________________________________ Maps-l mailing list Maps-l@lists.wikimedia.org <mailto:Maps-l@lists.wikimedia.org> https://lists.wikimedia.org/mailman/listinfo/maps-l
