Scaling IoT/Time Series/Metering Workloads with Azure Cosmos DB for PostgreSQL
Introduction : For many organizations around the world, the capture of consumption data is a common yet critical requirement. Some of these organizations struggle to manage the sheer volumes of data that they must capture and process. No wonder! We conservatively estimate that there would petabytes of such data globally and it is likely growing at a rapid rate. Today, many of the systems tasked to handle this data were designed decades ago, and many are likely hosted ‘on-premises’. We have seen, firsthand, such systems can be incredibly difficult to scale, costly to operate and complex to maintain. This all h...
Azure Cosmos DB design patterns – Part 3: Distributed counter
Over the years, customers have asked us for help in designing applications around specific scenarios they were trying to achieve. In some cases, these centered around implementing certain patterns using a JSON-based NoSQL database. Some of these patterns are very common in the NoSQL world, but not well understood by those new to NoSQL databases. Other patterns were very specific to the Cosmos DB service itself in demonstrating how to leverage specific capabilities to solve difficult architectural challenges. We’ve been capturing these patterns and sharing them with customers individually. We felt now was a...
Introducing Burstable Tier (M25) on Azure Cosmos DB for MongoDB vCore
Introducing the new burstable cluster tier (M25) in Azure Cosmos DB for MongoDB vCore, designed to cater to dynamic workloads with varying CPU usage patterns. Burstable SKUs provide an intelligent solution for small database workloads, offering minimal CPU performance during idle periods while seamlessly ramping up to full CPU power when faced with increased traffic or workload demands. This adaptability ensures peak performance precisely when required, all while delivering substantial cost savings. By reducing the initial price point of our service, we aim to facilitate user onboarding and exploration of Mon...

Announcing Dynamic Scaling Per Region and Per Partition for Azure Cosmos DB’s Autoscale
We’re excited to announce dynamic scaling per region and per partition (public preview) for all new Azure Cosmos DB accounts to help optimize and lower costs for your workload! By default, Azure Cosmos DB autoscale scales workloads based on the most active region and partition. For non-uniform workloads that have different workload patterns across regions and partitions, this can cause unnecessary scale-ups. Over the years, we’ve heard feedback from our autoscale customers that this can be pretty unforgiving for unpredictable workloads. With this improvement to autoscale, the per region and per partition au...
