Database / BetterDB Interview questions

What are the two Docker image variants for BetterDB Monitor?

BetterDB Monitor publishes two multi-arch (linux/amd64, linux/arm64) Docker image variants.

Tag	What it is
latest, X.Y.Z-no-ai	Default image with every monitoring feature, without the experimental local-LLM AI Helper's dependencies (~360MB compressed)
X.Y.Z	Adds the experimental AI Helper (bring your own Ollama), disabled by default via AI_ENABLED (~640MB compressed)

Both are built on node:20-alpine and contain the backend API plus the built frontend static files, served by Fastify.
