Show HN: Self tuning chat exposing it's semantic and agentic cache
The article discusses a new self-tuning chat system that utilizes semantic and agentic caching. It highlights the differences between Valkey, Redis, and Dragonfly, focusing on performance and functionality. Additionally, it provides insights into cache metrics and migration strategies between different database systems.
- ▪The chat system is backed by live documentation with semantic caching and tool result caching.
- ▪Valkey is compared to Redis and Dragonfly in terms of performance and capabilities.
- ▪The article includes information on cache metrics and how to migrate from Redis to Dragonfly.
