I’ve been working with imposm and Python, it’s fairly easy to parallelise. I’ve hit a performance problem when trying to associate the coordinates to the ways.
Creating a dictionary from coordinate_id to lat,long and then using it turns out to be really slow.
Do you know of any alternatives that I can use?
Has anyone used a C++ library, or even Scala, or PostgreSQL
Btw, I’ve been able to iterate through 39GB of PBF, almost the whole globe in 17 minutes on a 32 core machine. That’s the performance I’m looking for.
