Memory requirements for car+foot?

Hey all,

I’m trying to build a car+foot index and am consistently hitting OOMs. Building a car index so far has been fine. I’m on a box with 64gb of ram, setting Xmx and Xms to 55000m. Curious how much bigger of a box I need to build both indexes together.


If you want that other help you, please share your config.yml, command invoked, java version, system you used and e.g. logs including the stacktrace.


  • you can always exchange a bit speed for much less memory usage. Reduce memory to something like 30GB and use graph.dataaccess: MMAP_STORE.
  • if you try the latest master or wait for 1.0 there will be substantial reductions for the memory usage at import time
