What latency does Cosmos DB guarantee for reads and writes at the 99th percentile globally?

• A. Less than 5 ms
• B. Less than 10 ms
• C. Less than 20 ms
• D. Less than 50 ms

Answer: (B)

Cosmos DB is designed to provide low-latency performance, which is essential for global applications requiring fast access to data. The service guarantees that for reads and writes, the latency will be less than 10 milliseconds at the 99th percentile globally. This means that in 99% of the cases, read and write operations will complete within this time frame, offering consistent and high-performance data operations even when distributed across various geographical locations. This guarantee is a key feature of Azure Cosmos DB, which is highly regarded for its scalability, availability, and responsiveness. By ensuring that such performance metrics are met, Azure Cosmos DB supports applications that demand real-time processing, enhancing the user experience and ensuring that data-driven decisions can be made promptly. As a result, businesses can trust Cosmos DB to handle their workloads efficiently while maintaining a high standard of data access performance.
