Do you want to learn how to implement the refresh-ahead caching pattern with Redis Data Integration (RDI)? I wrote a blog post that illustrates this point exactly. 👉🏻 Read the full blog post here: dev.to/redis/from-p...

How many of you have been in a meeting where someone said, "We should use a vector database for this!" and everyone nodded, but you wondered... should we really? If this is you, then join me on October 13th at the @allthingsopen.bsky.social conference.

LLMs' fanciness and increasing intelligence don't change the reality—ultimately, they're just API calls. As such, they suffer from the same problems as API calls, such as throttling, timeouts, and exponential delays. 🔌 ⚡️ ➡️ But you can use clever ways to make LLM calls faster.

My take on this photo that is circulating out there: Replace the term "Data Engineer" for "Big Data Engineer" and everything else pretty much remains the same from 15 years ago. A couple of new technologies here in there—but nothing really disruptive. ¯\_(ツ)_/¯

Ricardo Ferreira @riferrei.com · 20/06/2025

Do you know who else loves to gossip? #Redis! Redis uses a combination of gossip protocol and distributed lock mechanisms to manage cluster state and node interactions. It provides a scalable and reliable foundation for vector search applications.

"Redis is the fastest vector database, but my dataset is large and I don't want to use big machines with lots of RAM as it is expensive, or having to shard my data with clustering." Fair enough. That's why for use cases like this you should use Redis Flex.

A simple key naming convention can transform @redis.io from "that confusing thing" to a powerful, intuitive data store that the whole team could leverage effectively. Thus... Instead of this: ➡️ SET home "123 Main St" ❌ Do this: ➡️ SET user:1001:address:home "123 Main St" ✅
