Hot Reloading (Watch Mode)

← Back to Martin Tile Server roadmap

Pick up new and changed data sources without restarting Martin.

When a new MBTiles file lands in a watched directory, a PostGIS table is published, or a remote PMTiles archive is replaced, Martin should refresh its catalog and any affected caches in place - keeping the server live while the data underneath evolves. The old WATCH_MODE was removed because it relied on a global lock per request; the replacement is a decentralised reloader per source type, coordinated through a TileSourceManager that serialises catalog updates.

Per-source status:

• (released) MBTiles - directories watched via OS file events; added/removed files appear in the catalog automatically
• (released) PMTiles - file additions and removals are picked up the same way
• (released) COG - Cloud Optimised GeoTIFF sources reuse the same reloader pattern
• PostgreSQL/PostGIS - discovery decoupled from init and source fingerprints landed; underlying trait refactor and the PostgresReloader itself are still open
