## Decision facts: write-you-a-vector-db

- **Adopt for:** write-you-a-vector-db is a C++ based educational project for building vector databases using the BusTub framework from CMU-DB's academic research. It lacks detailed licensing information.

## Choose when

### Choose carla if…

- Tags unique to carla: ai, artificial-intelligence, autonomous-driving, autonomous-vehicles.
- Also covers AI Agents, Model Training.
- More GitHub stars (14k vs 763) - visibility, not fit.

### Choose write-you-a-vector-db if…

- Tags unique to write-you-a-vector-db: bustub, database, tutorial, vector-database.
- When you aim to gain hands-on experience with implementing a vector database through an academic and instructive approach, utilizing the BusTub system from CMU-DB as the underlying technology.
- Leaner open-issue backlog (0).

## When NOT to use carla

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use write-you-a-vector-db

- If you require a production-ready vector database solution, as this is primarily a tutorial and not intended for direct deployment scenarios.
- When detailed licensing information is necessary for your project's compliance requirements, because the license of write-you-a-vector-db is unknown.
