🚧Roadmap

LOD is currently in a pre-release (v0.x) phase. As such, it should NOT be considered either stable or production ready in any sense.

  • In-memory, tunable LRU cache as first level

  • Redis cluster with configurable TTL as second level

• Dynamic query parameters

  • Allow configurable query parameters for tile URLs

  • Add to cache key for separate caching (osm/4/5/6/{osm_id})

• Configurable header proxying and deletion

  • Configurable headers to pull back into proxied responses from LOD

  • Configurable headers to delete from proxied responses from LOD

  • Configurable headers to inject into upstream tileserver requests

  • Content-Type and Content-Encoding are added by default

• Internal stats tracking

  • Separate authentication (bearer tokens and CORS)

  • Separate internal cache instances per proxy

  • Allow configurable query parameters for tile URLs

  • Separate stats tracking

• Administrative endpoints
