AI agent memory turns a stateless large language model (LLM) into an assistant that knows its users and delivers personalized, relevant responses. Implementing an agent memory layer can cut token cost by up to 90% and keep responses under 2 seconds (Mem0 benchmarks). Without memory, responses lose relevance, users repeat themselves, and token costs climb as raw history accumulates.

This p [...]

With the winter months winding down, it's a fitting time to introduce the general availability of Spring Data Valkey, a new open source Spring Data module that provides first-class integration between Valkey and the Spring ecosystem. Valkey adoption has expanded rapidly across cloud providers, Linux distributions, and enterprise environments. As organizations standardize on Valkey for caching, s [...]

Valkey is protocol-compatible with Redis and supports the full Redis 7.2.4 command API. That's one of its greatest strengths - existing clients are largely compatible, the learning curve is not steep. It's also, quietly, a problem for tooling.

Because compatibility means every tool built before Valkey existed technically "works" with it - tools that haven't been updated to take advantage [...]

The AWS Advanced JDBC Wrapper now supports automatically caching JDBC queries with Valkey, including Amazon ElastiCache for Valkey caches. Previously, developers who needed to cache JDBC query result sets had to manually write code to store and retrieve data from the cache for each query. Now you can automatically cache result sets from your Aurora and RDS PostgreSQL, MySQL, and MariaDB database [...]

Rate limiting is one of those topics that looks simple until you’re actually doing it in production. Implement a counter with the INCR command and a TTL and away you go.
