Cognitive Databases, Intelligent Data

No longer passive storage and query engines, databases are becoming active, intelligent participants in how modern systems interpret, connect, and act on data. As AI moves deeper into production and enterprises adopt generative and agentic architectures, the database layer is being reshaped to support semantic search, contextual retrieval, and real-time decision-making. Vector databases, semantic indexing, and AI-driven optimization are changing how developers work with both structured and unstructured data, while the line between transactional and analytical systems continues to fade under hybrid workload demands.This report examines these industry shifts in practical terms, exploring how relational, NoSQL, vector, and multi-model systems are coming together to support AI-native applications. Our research, guest thought leadership, and practitioner insights look at how teams are bringing vector search into production, updating architectures for AI workloads, and redesigning data pipelines around semantic and contextual intelligence.

How to Design Event Streams, Part 2

Oct 13, 2026 · Adam Bellemare

Really helpful follow up. The way you break down event design makes the tradeoffs much easier to reason about. How do you decide when an event should carry full state versus just an identifier?

How Open-Source BI Tools Are Transforming DevOps Pipelines

Oct 13, 2026 · Ayodele Johnson

Great read. Bringing BI tooling straight into the pipeline makes release health so much easier to see for the whole team. Which open source BI tool has worked best for you in a real DevOps setup?

Oct 13, 2026 · Stefan Wolpers

Loved this take. Adding AI on top of messy processes really does just speed up the mess. What was the first thing your team fixed before bringing AI in?

How a 30B Model Runs on Your Laptop

Oct 13, 2026 · Akash Lomas

Super helpful breakdown of how a 30B model can actually run on a laptop. The quantization part was explained really well. What laptop specs would you suggest for a smooth experience?

Kill the Worker, Keep the Research: Build a Recoverable LangGraph Agent on Temporal

Oct 09, 2026 · Akhil Madineni

Great write up. Keeping the research state durable when a worker dies is such a practical idea for real agents. Have you tried this with really long running research tasks yet?

When Search Started Breaking at Scale: How We Chose the Right Search Engine

Oct 09, 2026 · sunil paidi

Really enjoyed this one. The way you explained what changes once search hits real scale was easy to follow. Did you have to rethink your indexing approach much along the way?

Agentic Test Creation: From Plain-Language Requirements to End-to-End Test Cases

Oct 08, 2026 · John Vester

Great point about the authoring bottleneck in test automation. Having an agent read real requirements and existing test libraries feels like a practical step forward.

Mastering Azure Kubernetes Service: The Ultimate Guide to Scaling, Security, and Cost Optimization

Apr 14, 2026 · Jubin Soni, FBCS

Thanks, appreciate it! Great question, AKS autoscaling behaves similarly to self-managed Kubernetes since it uses the same HPA + Cluster Autoscaler components. HPA reacts quickly to spikes, but node scaling still has some lag due to provisioning time. AKS mainly makes this more reliable and easier to manage, but for sharp bursts, you may still need buffer capacity or tools like KEDA.
