summary
OpenTofu builds a drop‑in registry: an alpha on AWS Lambda + API Gateway that scraped GitHub, hit 5,000‑request rate limits and required layered caching, DocumentDB and async Lambdas before failing for short windows; the stable design instead stores JSON metadata in a GitHub repo, hourly GitHub Actions hydrate ~30,000 repositories into tens of thousands of files, syncs changed files to Cloudflare R2, and serves static endpoints — handling hundreds of GB, showing 99.9% cache hit and near‑zero maintenance while keeping human review for security.
