Do something smart on line 346 for on the fly counting. Though I think that I can generate the page that you provide maybe faster using just group by on an existing database... MonetDB uses string deduplication, perfect for this job ;) So that answers your: "So what I'm looking for is a simple (I really don't want to have to setup another Hadoop cluster) but still reasonably performant way to process the planet.osm to aggregate the needed data in a suitable format for importing it into a relational database."
