 | `UPDATE_STRATEGY` | `PARALLEL`, `SEQUENTIAL`, `DISABLED`   | `SEQUENTIAL`                     | Controls how index updates are handled. `PARALLEL` downloads the new index in the background then swaps with minimal downtime (requires 2x space). `SEQUENTIAL` stops Photon, deletes the existing index, downloads the new one, then restarts. `DISABLED` prevents automatic updates. |
 | `UPDATE_INTERVAL` | Time string (e.g., "720h", "30d")      | `30d`                            | How often to check for updates. To reduce server load, it is recommended to set this to a long interval (e.g., `720h` for 30 days) or disable updates altogether if you do not need the latest data.                                                                                   |
