Hi Peter at all,
I am planning to also use graphhopper's matrix API in
optaplanner-webexamples,
to generate the distance matrix for a number of locations in a VRP.
But I worry about my example flooding your server (which would make me a
bad citizen).
If I put no restrictions in it, and a user gives me a list n locations,
I am effectively asking for n² route distances....
For this reason, Google Maps has quota's in place, but those were really
annoying when I generated the data for this post:
http://www.optaplanner.org/blog/2015/03/20/3BugsInTheUltimateAmericanRoadTrip.html
because I needed 50 locations, which is almost 2500 routes and they only
allow 2500 routes per day
(so I had one shot per day to get it right).
Does GraphHopper have quota's in place?
If not, on what maximum number of locations should I restrict?
Note: I don't want to host my own GraphHopper server as part of
optaplanner-webexamples (because that would mean including 6GB of world
map data), so I 'd like to reach out to your service.
I do expect users to copy-paste the optaplanner-webexamples, but I 'll
put in a clear warning that they also shouldn't flood your server (=>
host their own server etc).
Wdyt?
With kind regards,
Geoffrey De Smet
OptaPlanner lead
