Or you can do what Taginfo does and just write it cleverly, so it just uses one host for an hour instead of 10 hosts for several hours. :-) I do agree that there are many use-cases for Hadoop & Co. But they also create a lot of overhead... Reminds me a bit of the Osmarender/Tiles@Home story: First we write a renderer thats horribly slow and inefficient. So we have to distribute the work load which makes it even more inefficient. Then to keep it going we invent more and more technology around it. Oh well, I liked Osmarender, spent quite a lot of time improving it and rendering maps with it. Sometimes its not about being efficient. :-) Jochen -- Jochen Topf [email protected] http://www.remote.org/jochen/ +49-721-388298 _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
