Introducing Redis 8: 15 years of Redis

Redis 8 is here. In this talk I go through a brief history of Redis. Then what's new in Redis 8. And wrap up with three short demos: full text search, vector similarity search, and probabilistic data structures.

1. Raphael De Lio 2025 Introducing Redis 8 15 years of Redis
2. Who has not heard of Redis before?
3. Redis is an actual database that happens to work really well as a cache.
4. 4 → Salvatore Sanfilippo → Web servers scaled easily, databases didn’t. → He wanted a database that was: - Fast - Fault tolerant - Horizontally scalable - Highly available 2008
5. Persistence Transactions Strings , lists, sets & sorted sets Master/Replica Architecture Hashes Pub/Sub Message Queue Lua Scripting Streams Automatic Failover Sharding Geoindexing Modules Client Side Caching 2009-2024
6. Redis Search Redis Time Series Redis Bloom Redis JSON The foundational infrastructure for building realtime apps
7. Probabilistic Data Structures Redis Query Engine (with Vector Similarity Search) JSON Data Structure Time Series Data Structure 2025 The foundational infrastructure for building AI apps Enhancements in performance
