[OSRM-talk] map matching service for a huge number of requests

[Patrick Agin]

Ok I found some explanations about libosrm here:
https://github.com/Project-OSRM/osrm-backend/blob/master/docs/libosrm.md
My second questions remains though: is libosrm mandatory for parallel use?
or could I use osrm-routed too (even if it is slower)?
All my code is written is Python so it could be great if I can integrate
python code to do the calls in parallel.
Thanks again
