Key Takeaways

What is Redis?

• Originally created in 2009 as a fast, horizontally scalable database
• Known primarily for caching, but it's actually a full database with persistence and transactions
• Redis 8 is now open source again with massive performance improvements (87% faster execution, 2x higher throughput)

Beyond Caching: Redis Use Cases

• Vector databases for AI applications (semantic search, caching, routing)
• Time series data for real-time analytics
• Geospatial indexing for location-based features
• Probabilistic data structures (Bloom filters, count-min sketch) for high-scale applications
• Streams for message queues and real-time data processing
• Session storage for distributed applications

AI & Vector Database Applications

• Semantic caching: Cache LLM responses using vector similarity (can reduce costs by 60%)
• Semantic routing: Route queries to appropriate tools without calling LLMs
• Memory for AI agents: Short-term and long-term conversation memory
• Recommendation systems: Power Netflix/YouTube-style recommendations

Getting Started with Spring

• Use start.spring.io with Docker Compose for easy setup
• Spring Data Redis for basic caching with @Cacheable
• Redis OM Spring for advanced features (vector search, JSON, etc.)
• New annotations: @Vectorize and @Indexed for automatic vector embeddings

Upcoming Events

• Spring One - 6 weeks away in Las Vegas
• Redis Hackathon - July 23rd via dev.to/challenges
