Change data capture (CDC) is the backbone of modern data platforms: Event-driven microservices, real-time analytics, incremental ELT, and operational alerts all depend on a reliable stream of change events. CockroachDB has long supported CDC with native changefeeds and familiar output formats like JSON and Avro. Now we’re adding Protocol Buffers (Protobuf) as a first‑class serialization option. If your organization standardizes on Protobuf for Kafka and downstream services, you’ll be able to plug CockroachDB in without glue code or format converters.

As modern applications expand across regions and clouds, the database layer often becomes the biggest constraint on growth. Global user bases, 24/7 availability expectations, and ever-evolving regulations have made the choice of database architecture more critical than ever. To help you make a better choice we’ve released a new whitepaper, CockroachDB vs. Amazon Aurora & DSQL: A Comprehensive Enterprise Distributed SQL Database Analysis. It takes a clear, technical look at how Amazon Aurora and Amazon DSQL database offerings stack up against CockroachDB when it comes to scale, resilience, and operational simplicity.

In today’s AI-driven world, enterprises need more than just fast queries or scalable storage, they need a unified data foundation that can power both real-time transactional workloads and vector-based AI applications. Traditionally, these two worlds have lived apart: transactional databases handled the operational data, while vector stores powered AI search and semantic similarity. But that separation comes at a cost: data fragmentation, slow pipelines, and operational complexity. What if you could have both in one system?

Enterprises are operating across a fragmented infrastructure landscape that spans on-prem, hybrid, and multi-cloud environments. Their databases need to move just as freely.

AWS’s us-east-1 region stumbled last month, and the businesses buckled. Our customers didn’t. CockroachDB clusters continued serving global traffic without disruption – proving what “resilience by design” really means.

In our recent webinar, “From Oracle to CockroachDB: Lessons from Real Migrations”, technical experts Rohan Joshi and Alistair Parry walked through how real-world organizations across industries migrated mission-critical workloads from Oracle to CockroachDB. Through this talk, live demo, and engaging Q&A, the audience learned which Oracle workloads are a great fit for CockroachDB, how to tackle schema conversion and PL/SQL refactoring, and how our MOLT (Migrate Off Legacy Technology) toolset accelerates the process.

At Cockroach Labs, we are relentlessly focused on providing a database that is not only powerful and resilient but also fundamentally secure. We’re excited to announce a noteworthy milestone in our commitment to enterprise security and our integration with the Microsoft Azure ecosystem: CockroachDB Cloud now supports Customer-Managed Encryption Keys (CMEK) for Azure, along with Egress Perimeter Controls.
