Azure Cosmos DB Migration from MongoDB (RU) to Azure DocumentDB Is Now Generally Available!
After a successful public preview, we’re excited to announce the General Availability (GA) of online migration from RU-based Azure Cosmos DB for MongoDB to Azure DocumentDB (with MongoDB compatibility). This capability makes migration fast, simple, and cost-free—all through the Azure portal. Why This Matters If you’re running workloads on RU-based Cosmos DB for MongoDB, you can now move to Azure DocumentDB without downtime or extra cost. The GA release ensures a seamless experience: everything happens online, directly in the Azure portal, with no hidden charges or additional tools. What You Get Migration is d...

Now Available: Sort Geospatial Query Results by ST_Distance in Azure Cosmos DB
Azure Cosmos DB’s geospatial capabilities just got even better! We're excited to announce that you can now sort query results by distance using an ORDER BY ST_DISTANCE(...) clause in the NoSQL query language while leveraging a spatial index. Why is this important? Previously, you could use ST_DISTANCE in projections or WHERE clauses to filter results within a radius, for example, finding all restaurants within 5000 meters. But if you wanted to sort those results by the distance, you had to pull the data client-side and handle sorting manually. Now you can now do it directly in your query! Azure Cosmos D...
Query Advisor for Azure Cosmos DB: Actionable insights to improve performance and cost
Azure Cosmos DB for NoSQL now features Query Advisor, designed to help you write faster and more efficient queries. Whether you’re optimizing for performance, cost, or scalability, Query Advisor provides actionable recommendations to help you get the most out of your data. Why Query Optimization Matters Azure Cosmos DB’s SQL API is flexible and expressive, allowing developers to query JSON data with familiar SQL-like syntax. But as applications grow in complexity, small differences in query structure can have a big impact on performance and Request Units (RUs). For example, two queries that return the same r...

Failures Happen in Cloud, but how Azure Cosmos DB keeps your Applications Online
In this blog, we'll discuss how Azure Cosmos DB is engineered for resilience and how it ensures high availability when failures happen in the cloud. Why does it matter ? The only thing that’s constant in distributed systems is failures. No cloud platform is immune to failures — from regional outages and transient network blips to human errors or hardware faults. What defines resiliency & high availability isn’t the absence of failure, but how systems anticipate, isolate, and recover from them. For many internet applications and services, the database is the first layer (looking bottoms-up) that needs to...
