<div class="moz-cite-prefix">Hey Mark,<br>
<br>
restarting could be done in several 'flavours'. One use case would
be to refresh the files in-memory and just swap the GraphHopper
instances which requires CPU and RAM on the same machine but
involves no down-time - so very nice but only for rather small
areas. Another usecase could be as you describe but the problem is
that the import and preparation could be too long to be
acceptable.<br>
<br>
So I currently don't think this can be handled within GraphHopper
itself and is easily implemented outside of it.<br>
<br>

Peter.<br>

<div dir="ltr">Hi Peter, I am just installing the new Graphhopper
in a windows Server environment and it works well under cygwin
<div><br>
</div>
<div>I intend to update the graphs on a weekly basis (2G Asia
pbf) and a simple question, </div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>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.<br
