"I'll know it when I see it" is the classic car buyer's line, but it's also the one thing old-school search bars totally fail to deliver. Traditional keyword search fails when a customer wants a car that "looks like this photo from Fast and Furious." This is where vector search comes in, transforming unstructured data into mathematical vectors to find semantically similar items.

At its foundation, CockroachDB depends on a key-value storage engine called Pebble. In CockroachDB v25.4, the storage team introduced value separation within Pebble: an optimization that improves compaction efficiency for many workloads. Value separation increases the throughput of the core of CockroachDB, the storage engine, by up to ~50%, depending on the workload, through algorithmic improvements. It reduces redundant I/O, reducing cost-to-serve at scale. We’ll look at how Pebble represents data today, what’s changed, and how that translates to database efficiency.

In this blog post, we dive into the significance and benefits of RAG applications first. Then we explore the advantages of leveraging CockroachDB, a highly scalable and resilient distributed SQL database, as the foundation for building efficient and robust RAG applications. To illustrate the practical implementation, I’ve created a knowledge base chatbot.

In today’s always-on, global applications, raw speed is no longer enough. Modern enterprises demand not only blistering transaction rates but also unwavering stability when the unexpected strikes; whether that’s a network hiccup, a failing disk, or an entire data center going dark. With organizations averaging 86 outages a year, failures are the norm today. But traditional benchmarks like TPC-C only tell you how fast a database runs in perfect conditions, or sunny days. They leave out the more important story of what happens when things go wrong.

A few months ago Cockroach Labs turned 10, and this release celebrates 10 years of continuous distributed SQL innovation. We’re introducing even more performance and scalability improvements and AI vector indexing, along with many other new features and enhancements to both self-hosted and cloud offerings in the areas of change data capture (CDC), security, observability, and migrations.

Database migrations are complex, and ensuring the migrated data is 100% correct is critical. After all, a migration isn’t over until you feel confident and comfortable cutting over to the new infrastructure. To streamline migrations, Cockroach Labs created the MOLT (Migrate Off Legacy Technology) toolkit, which includes three tools that improve different parts of the user journey.
