Nice question there.
I think it is not possible to process really big files due the nature of ch library (+ it has an issue corresponding to performance.
Complex graph topology could be a problem too: since a lot of shortcuts could be created (x2 of edges number).
I think the steps to improve this tool are:
- Reach max performance on ch library when it generates shortucts:
- Better heuristics
- Threaded batch processing
- Something else like preallocation of priority queues memory for local Dijkstras (witness search)
- Need to do some parallelism on file loading (but be careful, since graph data structure is not thread safe for inserting vertices and edges)
