Neo4j for Beginners: Pros and Cons, Based on Social Networks
summary
Live coding shows Neo4j modeling a social network: CSV import loads 100 person nodes and creates directed friendship edges, Spring Data Neo4j connects over Bolt with a browser on separate ports, queries use Cypher and APOC/GDS libraries, and explain/profile reveal DB hits. Claim: Cypher beats SQL on deep joins with orders‑of‑magnitude speedups; tradeoff: graph needs ~3x storage. Useful utilities: APOC ~450–650 procedures and loaded 100 nodes via CSV.
