AI applications can no longer rely on classic databases.
Specifically:
- semantic search
- chatbot memory
- recommendation systems
→ a vector database is required
But the biggest mistake: Hosting a Vector DB just like a regular database.
1. Core Concept
Data → embedding Search → similarity search
2. Memory Requirements
Numeric Example #1
| Data | Size |
|---|---|
| 1 embedding | 1–2 KB |
| 1M records | 1–2 GB |
RAM is a critical factor.
3. Latency
Numeric Example #2
| System | Duration |
|---|---|
| SQL | 50–100 ms |
| Vector | 100–400 ms |
4. Disk vs RAM
- RAM → fast
- Disk → slow fallback
5. Production Scenario
BEFORE:
- 8 GB RAM
- slow
AFTER:
- 32 GB RAM
- fast
6. Benchmark
| Metric | Poor | Optimized |
|---|---|---|
| Latency | 800 ms | 120 ms |
| UX | poor | good |
7. Index
- HNSW
- IVF
Trade-off: speed vs accuracy
8. Implementation
db.insert({"vector": embedding})db.search(query, top_k=5)9. Reality vs Hype
Hype:
- just install a vector DB
Reality:
- RAM is required
- tuning is required
10. Risks
- slowness
- cost
- wrong index
11. Trade-off
| Model | Pros | Cons |
|---|---|---|
| small | cheap | slow |
| large | fast | expensive |

14. Conclusion (CTA)
Vector DB requires the right infrastructure.
If you have a performance problem: submit an infrastructure analysis request.
