A PhD is when your supervisor gradually becomes convinced that you know what you’re doing, and you gradually become convinced that neither of you does.

🔎🤖LangSmith Insights Agent
Really excited to launch our first in-product agent
This agent lives inside LangSmith and combs through traces, giving you insights into:
🧑🤝🧑how users are using your agent
⁉️how your agent may be messing up
🛃{your custom insight here}
The problem we saw was that people were launching agents... and didn't know how their users were actually using them! You put a chat box in front of people, and they may ask it anything - the surface area for agents is often super wide
In addition - agents would fail silently. They could give a bad response - this wouldn't show up in error logs, but its good to know.
If you know what look for, you can set up LLM as a judge evaluators. But what if you don't? (most people don't initially)
The best way to figure this out - as @HamelHusain says - "look at your data". But LLMs are really good at looking at your data! So can they do it for you?
This is exactly what insights agent attempts to do. It's live in LangSmith today. You can read more about it here: blog.langchain.com/insights-…

The thing people don’t get too is it doesn’t just like hard fail in an easy to understand way where you can just easily cycle the node. It fails in very annoying ways like suddenly getting very slow, sometimes, maybe, if you’re not looking at it, on Wednesdays

I'm speaking at #Current24 next week! Come around for an overview of the CDC ecosystem + a spoiler of a new standalone, low-footprint CDC service built using Rust and @ApacheArrow. 👀

Are you performing complex queries on operational data? Materialize costs 1/20th what Aurora PostgreSQL read replicas do, while achieving 100x greater throughput and 1000x lower latency. Read our full analysis -> materialize.com/blog/materia…

Materialize vs. PostgreSQL: Materialize delivers 100x greater throughput with 1000x lower latency. Materialize wins for OLTP offload. Check out the benchmarks in our new blog -> materialize.com/blog/perform…

I've always found the conversation around databases and inconsistency challenging to distill into simple terms. This is my attempt to build some simpler intuition.

We're back with another episode of Software Huddle. Join us for an engaging discussion.
Operational Data Warehouse with Nikhil Benesch 🎉
Today's episode is with Nikhil Benesch, who's the co-founder and CTO at @MaterializeInc, an Operational Data Warehouse.
Materialize gets you the best of both worlds, combining the capabilities of your data warehouse with the immediacy of streaming. This fusion allows businesses to operate with data in real-time.
We discussed the data infrastructure stuff of it, how they built it, how they think about billing, how they think about cloud primitives and what they wish they had.

My timeline is full of PartyRocket related stuff. With all that noise, I must have missed the announcement for the service that converts a draft into a proper presentation. Can someone please remind me? It's kind of urgent... #kafkaSummit
Nice! Bonus points for printing it out ♥️
This morning read - Best practices for right sizing your Apache Kafka clusters to optimize performance and cost by @sthmmm. Steffen talks about most common resource bottlenecks and getting to a suitable cluster based on requirements. More in 🧵 #Kafka @apachekafka

"They said I couldn't empower an analytics engineering team to take a rules-based fraud detection approach down from 30 min batch to 3 seconds streaming, all with SQL and dbt, and I took that personally"
Steffen Hausmann retweeted
A large part of my role @MaterializeInc is building a real-time data warehouse *without* the typical complexities of streaming.
I'm excited to share how easy it is at #datacouncil24 with a talk titled "Real-Time Analytics for Small Data Teams".
