Join Dan Vega and DaShaun Carter for the latest updates from the Spring Ecosystem. In this episode, Dan and DaShaun are joined by Redis Developer Advocate, Raphael De Lio. Join us as we explore Redis’s ever-growing role in the Spring ecosystem. We will look discuss its common and foundational use cases, then dig into new and exciting use cases, including similarity search, the cutting-edge vector data type, and how Redis is becoming a key player in AI-driven solutions. Get ready to discover the latest ways Spring developers are leveraging Redis to build highly performant and intelligent applications. You can participate in our live stream to ask questions or catch the replay on your preferred podcast platform.

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
