Maps nodejs server for vector-based tiles and snapshots, designed for Wikipedia and other sites. It ties together a number of MapBox components for vector and raster rendering based on Mapnik 3, and uses service runner for scalability, performance monitoring and stability.

Generating tiles from the SQL queries sometimes requires a considerable time, often too long for the web request. Tilerator is a multi-processor, cluster-enabled tile generator, that allows both pre-generation and dirty tile re-generation.

Scheduled generation job waits in the queue (kue) until it is picked up by one of the workers. The worker will update job progress, as well as store intermediate data to allow restarts/crash recovery.

Tilerator is an unprotected Admin tool, and should NOT be exposed to the web. By default, tilerator only accepts connections from the localhost. It is recommended that it is left this way, and used via a port forwarding ssh tunnel with ssh -L 6534:localhost:6534 my.maps.server
