Integrating Neo4j with Google Gemini: Architectural Patterns for AI Agents
summary
Shows concrete integration patterns: natural language → Cypher where Gemini generates validated Cypher for Neo4j (AuraDB or self‑hosted) via Vertex AI/Cloud Run, and graph as long‑term memory using temporal knowledge graphs to persist episodic and semantic context with TTL/decay policies. Demonstrates a hybrid graph+LLM reasoning flow that ranks candidates via graph traversals then asks Gemini to explain, reducing hallucinations and improving recommendations and incident analysis. Covers caching, secret managers, retries, autoscaling and practical latency vs. explainability tradeoffs.
