Render Queue Worker — diagram

A small daemon that turns a watched directory into a render job queue. Jobs are JSON files; claiming a job is an atomic mv; recovery after a crash means moving files back. No database, no broker, no web UI.

Design notes

  • The filesystem is the queue — mv gives atomicity for free.
  • systemd handles restarts, logging and memory limits.
  • Notifications go out through a Telegram bot on job completion or failure.

Status

Running in production on my render node since mid-2026. Next step: a --dry-run mode that estimates job duration from scene statistics.
