Description
- use zsync to update routing data from the server
- like this, only changes would be transferred, making frequent routing data updates feasible
- packs for large countries can take up multiple GBs
- zsync: http://zsync.moria.org.uk/
- drawbacks:
- needs to store two copies of the routing data
- one archive for direct download
- one in uncompressed form + zsync control file for updates only
- needs zsync files for all files
- on the other hand as zsync won't overwrite the file until the download is finished, working on multiple smaller files helps
