Admission control is the system in CockroachDB that prioritizes work during different types of node overload. In a properly sized cluster, where the work does not exceed the resource capacity, all work proceeds uninterrupted and effectively receives equal priority.

What is distributed SQL? An evolution of the database
Distributed SQL combines the consistency and structure of the early relational databases with the scalability, survivability, and performance first pioneered in NoSQL. Distributed SQL databases like CockroachDB use this architecture to provide a single logical database that replicates data across multiple physical nodes at any scale, on any infrastructure, and anywhere in the world.

Prevention > Recovery: Physical cluster replication
Applications built on a traditional failover pattern with two data centers (and no access to a third on-prem or cloud region) used to face challenges in ensuring high resilience with CRDB. New in v23.2, physical cluster replication functionality now allows limited distribution applications to survive full cluster failures — with RPO and RTO measured in seconds rather than minutes.

How we stress test and benchmark CockroachDB for global scale
How do we know what our database is actually capable of? We test it. A lot. Here's a summary of some of the tests and benchmarks we run regularly to ensure CockroachDB is performant even at global scale.

How to build an inventory management system that scales (with reference architecture)
One of the biggest technical challenges of inventory management is keeping data consistent in real time, or as close to it as possible. Particularly with larger operations, this is vital to avoid “overselling” scenarios that can cost the company money or damage its reputation.

Top Three Reasons Behind Database Migrations
I recently moved into a new house. Boxes are everywhere. Little pieces of styrofoam surprise me everywhere I go. There are many noises I don’t recognize or understand. And the drill I’d forgotten I even owned now occupies a prime spot on my kitchen counter. I use it daily. I didn’t move to a new house because I thought moving would be fun, or even easy. I knew it would be a lot of work. I moved because my family needed more space. Which is just one of many reasons someone might decide to endure the pain of moving: Cost. Quality of life. Proximity to the people/places that are important to you.
