Understanding tile caching execution and prioritizing

When TopoPlanner requests a map tile, it looks for it by following caching levels:

  1. Decompressed raw bitmap tiles, in memory
  2. Compressed tiles in their native format, in memory
  3. Local SQLite/CE database on users' hard-disk
  4. Second level cache on LAN, MySQL/MsSQL server (optional)
  5. Global servers (Google/Bing/etc), with read-only access
