Pros & cons
Redis
- Extremely fast in-memory performance
- Versatile data structures for caching and queues
- Wide client and cloud hosting ecosystem
- Not a primary relational system of record
- Memory cost and persistence trade-offs
- Licensing / product naming has evolved
Neo4j
- Best-in-class graph model and Cypher
- Great for knowledge graphs and recommendations
- Aura managed option plus self-host
- Not a drop-in SQL/RDBMS replacement
- Graph modeling mindset required
- Cost can rise for large Aura workloads
