From Real-Time Analytics to AI: Your Azure Cosmos DB & DocumentDB Agenda for Microsoft Ignite 2025
Microsoft Ignite 2025 is your opportunity to explore how Azure Cosmos DB, Cosmos DB in Microsoft Fabric, and DocumentDB power the next generation of intelligent, planet-scale applications. Whether you’re building real-time analytics pipelines, optimizing MongoDB-compatible workloads, or implementing AI-driven architectures, these technologies are at the heart of modern innovation. This year’s sessions feature hands-on labs, advanced breakouts, and inspiring customer stories from companies like Sam’s Club, Veeam, and Sitecore, showing how they leverage Azure Cosmos DB and DocumentDB to deliver speed, re...
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
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 & reliability isn’t the absence of failure, but how systems anticipate, isolate, and recover from them. Here is a deep dive on how, we at Azure Cosmos DB, think about resiliency amidst the failure modes that can happen in cloud. For many internet applications and services, the database is the first layer (looking bottoms-up) that needs to be highly available, durable, whatever happens und...
From Backup to Discovery: Veeam’s Search Engine Powered by Azure Cosmos DB
This article was co-authored by Zack Rossman, Staff Software Engineer, Veeam; Ashlie Martinez, Staff Software Engineer, Veeam; and James Nguyen, Senior Principal Cloud Solution Architect, AI/ML, Microsoft. Don't miss: Hear all about about Veeam's AI-powered semantic search use case and architecture setup at Ignite! Join us for "How Veeam delivers planet-scale semantic search with Azure Cosmos DB" Thursday, Nov. 20, 1 PM PST. Most people think of data resilience as two steps: backup and recovery. Backup creates a copy. Recovery brings it back when disaster strikes. But what if you can’t find the file...
Bringing Context to Copilot: Azure Cosmos DB Best Practices, Right in Your VS Code Workspace
Developers love GitHub Copilot for its instant, intelligent code suggestions. But what if those suggestions could also reflect your specific database and workload patterns? That’s now possible with a new feature in Azure Cosmos DB for VS Code. Starting today, when you connect to your Cosmos DB account in VS Code, the extension automatically deploys an azurecosmosdb.instructions.md file to your user profile folder, ensuring it works seamlessly across all workspaces without requiring duplication in each project. This file acts as a context provider for GitHub Copilot a bridge that helps the AI understand your ...
