Hiya, I need node geometry (lat,lon) information available as I process the ways in an OSM file through an Osmium handler (I'm using C++). The FAQ says I can use a few ways to store the nodes while processing. I just wanted a bit of clarification... The docs say that mmap and FixedArray both require 64-bit systems to address enough memory for all the nodes (I'm not working on the planet dataset, but for arguments sake let's assume I am). They also say that mmap writes to file -- so I understand that I need 64-bit for FixedArray to address all that memory, but if mmap writes to file, shouldn't it work on systems with less memory? I don't know where the cut off is -- ie. how much memory is addressed before it starts writing to file. It would be great if someone could explain this a bit further.
