Lite version of OSRM instance

[KushnirDV]

Is it possible to disable some not used data to get more lite (less size at least 2 times) OSRM instance?
We use only rute and nearest API services. The reasson is to boot two backend OSRM entities on our server.
Will thankful for your answer.

I guess you are asking if you can decrease dataset size?

Related to #5838 (scoped more specifically on potentially removing the guidance dataset).

@KushnirDV if you use steps=true in your Route API response, then all the data is used.

There are some files generated during osrm-extract that can be deleted, but I don't have a handy list. One way to get the actual list of used files is to use strace and look for open() syscalls to get all the filenames that are used by routing.

If the issue is memory consumption, then you can use the --mmap option to lazy-load data from disk. If you perform a warmup routine with a typical set of queries, this can help you use just the minimum RAM needed for fast queries.

You are doing a realy good job.
I will compile OSRM version higher than 5.20 to be able to use --mmap and will start generetion a new routing.
Thanks for fast and helpfull support.
