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.

How Nightfall.ai simplified their architecture for metadata storage
For organizations that want to avoid risk the first step is often to safeguard their most important asset: data. Data loss usually happens by accident (primarily human error and system failures) and not because of malicious intent or bad actors. Maybe an employee neglects to update their software, or an entire cloud region goes down, or there’s an unexpected influx of traffic that the company wasn’t prepared for – we’ve all heard of or have been part of these stories. Recently, data protection has become more complicated because businesses are running many applications in the cloud that employees are accessing on a daily basis. The more applications, the more risk.

Why we need a multi-cloud database, and how to build one
In our State of Multi-Cloud 2024 report, we were a bit surprised to find that half of our respondents said their companies were already multi-cloud, and of those, half had already begun working with complex multi-cloud deployment patterns like deploying a single workload across multiple clouds. What are the benefits of that sort of complex deployment, and how can it actually be achieved in the real world to bring the advantages of multi-cloud to mission-critical workloads like your transactional database workloads?

A sports betting app saved millions switching from PostgreSQL to CockroachDB
The challenges facing sports betting platforms are rigorous: they have to be fast and consistent in a way that’s similar to high-frequency trading platforms. At the same time, they have a variety of data-locality requirements to comply with depending on which states or countries they serve. In this blog, we’ll look at a real-world example of a North America-based sports betting platform that designed a gaming and sports betting architecture that not only meets the performance, consistency, and compliance requirements of the industry; but also enabled the business to swiftly enter new regional markets without requiring a massive engineering effort.

No Dirty Reads: Everything you always wanted to know about SQL isolation levels (but were too afraid to ask)
Every relational database needs to establish a balance between accuracy and performance. Transaction isolation levels have a direct, though often unrecognized, impact on both.
