Record the full reasoning path (GraphQL service, Arrow Flight, raw SSH, forced-command synthesis) and specify read-only enforcement as five fail-safe layers: key-per-operation, SELECT-only statement gate, read-only OS user, engine hardening, resource caps. Promote 'SQL is the contract' to a top-level design principle.

# Swarm House
|
|
|
|
**An on-prem data platform for autonomous drone swarms** — a design proposal from a DevOps perspective.
|
|
|
|
A fleet of drones flies fully autonomously: no internet uplink, no external access, all data stays inside the swarm. Each drone collects high-rate sensor telemetry and runs on-board video object detection. The swarm must exchange just enough state to coordinate flight, store everything else locally, and hand its data over to a ground warehouse after landing — reproducibly, securely, and at scale.
|
|
|
|
This repository describes how to build, deliver, test, and operate that platform: the storage layout, the sync strategy, the network trust model, the CI/CD chain, and the simulation environment that makes it all testable without touching real hardware.
|
|
|
|
## Design principles
|
|
|
|
1. **Every drone is autonomous.** No cluster orchestrator spans the swarm; intermittent mesh connectivity makes that an anti-pattern. Coordination happens through data exchange, not through a control plane.
|
|
2. **One storage format on every floor.** Parquet + DuckDB with an identical Hive-partitioned layout on the drone, in the ground warehouse, and in the dev environment. Flight offload is a plain mirror operation.
|
|
3. **Sync results, not raw data.** Only derived state (position, attitude, detections) crosses the air. Raw telemetry stays on local NVMe until the drone lands.
|
|
4. **Event-driven, not polled.** New derived data triggers downstream actions through hooks; nothing burns cycles asking "anything new yet?".
|
|
5. **Zero trust, provisioned ahead.** Keys are issued per device before deployment; nothing joins the swarm at runtime. Dev channels are physically absent from production builds.
|
|
6. **The whole fleet has one version.** A release manifest pins every image digest, model weight, schema, and config. Rollback is atomic.
|
|
7. **SQL is the contract.** Peer data access is read-only DuckDB SQL over SSH forced commands — the query language already lives on both ends, so no service, port, or protocol is invented for it.

## Runnable parts
|
|
|
|
| Component | Purpose | Stack |
|
|
| --- | --- | --- |
|
|
| [`simulator/`](simulator/) | Virtual drone fleet: generates realistic telemetry through the same Parquet/DuckDB pipeline a real drone would use; N drones via Docker Compose | Python, pyarrow, DuckDB |
|
|
| [`prototype/`](prototype/) | 2D top-down swarm visualization: drones, obstacles, inter-drone links with live transfer metrics | React, TypeScript, Vite, SVG |
|
|
|
|
## Quick start
|
|
|
|
```bash
|
|
# Spin up a virtual swarm of 10 drones
|
|
cd simulator && DRONE_COUNT=10 docker compose up
|
|
|
|
# Run the visualization
|
|
cd prototype && npm install && npm run dev
|
|
```
