Announcing Azure Cosmos DB custom routing endpoints for Azure IoT Hub – GA
We are very happy to announce the general availability for Azure Cosmos DB custom routing endpoints for Azure IoT Hub. Many IoT solutions require extensive downstream data analysis. You have to seamlessly push the data into hyperscale databases quickly. For example, intelligent transport systems have a constant inflow of a continuous stream of data. This data must be analyzed even as it is being written into the database. We have seen multiple scenarios in manufacturing, automotive, and other IoT solution-focused industries that require hyperscale databases. These solutions need extremely high throughput to...

Azure Cosmos DB design patterns – Part 1: Attribute array
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...
4 Design Patterns to Deal with Large Item Sizes in Azure Cosmos DB for NoSQL
Introduction A recommended best practice in Azure Cosmos DB for NoSQL is to avoid overly large item sizes. An Azure Cosmos DB item can represent either a document in a container, a row in a table, or a node or edge in a graph, depending on which API you use. Though the maximum size of an item allowed in Azure Cosmos DB for NoSQL is 2 MB, it is strongly recommended to restrict item sizes to 1 - 5 KB. This blog post covers multiple approaches that you can use to model large objects within your Azure Cosmos DB-backed application.  This post draws from our experiences of collaborating with different Software En...
