Is there a simple way to add new data (additional pbf file) to an already working install without rebuilding all the graphs?
Currently we don’t support multiple pbf files in a single ors instance.
If the files don’t overlap you could merge them and build on the merged file. But that also requires rebuilding.
You could have a separate ors instance for it and do some middleware magic that directs the request to the correct instance depending on the location.
Feel free to open an issue for supporting multiple pbfs.
