I'd suggest taking a look at tirex.
May I ask what the practical advantages to using tirex over renderd are?
I'm not sure if there are practical reasons but tirex seems beeing under active development while i'm not sure about this in renderd. It sounded to me like the next logical step.
So given that tirex still seems a bit experimental, it might not be a bad idea to experiment with it on dev.osm.de for the moment and continue to use renderd on ptolemy for the moment.
Okay, let's do so. I'm 50:50 about tirex & renderd as I just don't know enough about them.
In adition I don't think that the toolserver should host the 250+ language styles - this is in my eyes the job of the live cluster (ortelius& cassini).
Are there any plans on setting up the live cluster? It does in some way
Give me some access and I'll see what I can do.
sound like those services shouldn't necessary be on the toolserver, but then it makes sense to test it on the toolserver first and to me (not really knowing anything about the wikipedia side of things) it appears as if WMA and geohack are still running on the toolserver too, even though they have been "in production" for a while.
How about getting up the map rendering for the languages of the 10 (or maybe 25) biggest Wikipedias. This would not create as much load on the toolserver as 250 styles and we can test most multilingual rendering things.
That would be: en, de, fr, it, pt, nl, ru, pl, es, ja
Regarding the use of the hstore: osm2pgsql HEAD currently can do an hstore import, but it can only import all tags into one hstore and additionally some tags into their own columns. Our testings points out, that tag-lookups are getting really slow for often used tags.
So I would sugest a small osm2pgsql stylesheet with the most used tags (amenity, highway and such), especially those that are often uses for lookups. Columns that are used most the time for value-lookups (addr:*, name, name:*, wikipedia:*) sould be imported into the hstore.
I'd like to do this as well as I'd like to help out in getting the live cluster up.
