[GraphHopper] Updating Graphs

[Markware Software Services]

Hi Peter, I am just installing the new Graphhopper in a windows Server
environment and it works well under cygwin

I intend to update the graphs on a weekly basis (2G Asia pbf) and a simple
question,

If I download the new pbf file and overwrite the old file, will graphhopper
automatically detect the new file (date stamp diff) or do I need to stop
graphhopper, delete the graphs and restart graphhopper to trigger the
rebuild?

If it is the second case, I guess at some stage in the future it may be
useful to have some kind of semaphore file or other trigger that could
cause the rebuild of the graph without having ot kill graphhopper to help
with the background automatic updating? Of course, the system woudl have to
return Not Available to any calls whilst the graph was being rebuilt.

Am interested in your thoughts on the best way to go.

Cheers
