We built a new 1-day workshop on building Multi-Agent AI Apps with @AzureCosmosDB Learn using LangGraph (python) or Semantic Kernel Agents (C#), or both. Code is here. Deploy/run full sample on main branch or use start branch for workshop. github.com/AzureCosmosDB/…

12 years ago today, on this boat sailing around Stockholm Harbor, Global Azure Bootcamp was born.

Cosmos DB now runs natively in Microsoft Fabric! Blend NoSQL + SQL, stream real-time analytics into OneLake, and power BI with Copilot—all in one unified platform. #CloudData meets #MicrosoftFabric 🧠 Learn more. 🔗 msft.it/6014s6J9I

🚀 Improve your #AzureCosmosDB query performance with Global Secondary Indexes! GSIs let you run efficient queries across different partition keys—no manual sync, no heavy lifting. 🎥 Watch Mark Brown (@markjbrown) & Justine Cocchi explain: youtu.be/pl74ouvEe9Y #NoSQL #MicrosoftBuild

@jeffwilcox @davidfowl LOL 🤣

If you're not using containers for deployment, what's stopping you?

@MadhuGilla Thank you. More episodes coming this Summer.

@markjbrown Thank you @markjbrown , I wanted a very simple tool for our devs and admins. Love the cosmos db show by the way !!!

Was struggling with copying document from one comosdb to another, so Vibe coded "CopyCosmosDBContainer" tool to solve the headaches of migrating data between Azure Cosmos DB containers—whether within the same database or across accounts. give it a try github.com/madhugilla/Cop…

Looking for something new to learn? Python + Azure Cosmos DB might be your next move. With AI everywhere, data skills are more critical than ever. Your AI app can only be as good as your data. Just released a 5-part series covering the fundamentals you actually need: Data modeling: youtu.be/9sJGxigUido?fe… Client configuration: youtu.be/D7GKPIx_ARg?fe… Async operations: youtu.be/jmK5msNic9c?fe… Batch operations: youtu.be/I0zH-Zb8d7M?fe… Error handling & logging: youtu.be/e9K7_HPY2Aw?fe… Everything's wrapped up in a template you can deploy immediately (or take apart for the bits you need): github.com/madebygps/cosm…

@AlaskaAir Yes, mobile app has same issue. Will DM you.

@markjbrown Are you having the same issue on the app? Please send a DM so I may get more information. - Nadine twitter.com/messages/compo…

@AlaskaAir is your site having issues? Getting persistent HTTP 406 errors.

@AlaskaAir Yes, both. Issue persists.

@markjbrown 🤔 I am not aware of any issues. Did you clear your cache and cookies? - Nadine

@slimstinator Nice pants polygon 🙂

@markjbrown Thanks Mark, working on recording "Points of Interest" (currently shown as flags) for Superyachts in our Compass application

@markjbrown Question I am struggling with. In CosmosDB if I am storing geojson, should the PartitionKey be in the root or in Properties? Example in image, does this look right? If I try and move the VesselID into the root, it doesn't let me update

Build C# multi-agent AI using Semantic Kernel + Azure Cosmos DB! 🤖 • Agent-based architecture • Cosmos DB as vector & transactional store • Real-world use cases + implementation insights Watch → youtu.be/q0R5fPFdlrw #SemanticKernel #AzureCosmosDB #dotnet

🚀 Everything new in #AzureCosmosDB from #MSBuild 2025! Catch Kirill Gavrylyuk (@kirillg_msft) & Mark Brown (@markjbrown) as they break down all the latest: 🔹 AI agent integration 🔹 Global Secondary Indexes 🔹 Smarter search 🔹 MongoDB upgrades & more 📺 devblogs.microsoft.com/cosmosdb/azure…

Cost-Effective, Low Latency Vector Search It looks like a pretty good read for developers looking to scale vector searches. Proposal: Integrates DiskANN (a vector indexing library) inside of Azure Cosmos DB NoSQL (an operational dataset) that uses a single vector index per partition stored in existing index trees. Benefit: "It supports < 20ms query latency over an index spanning 10 million of vectors, has stable recall over updates, and offers nearly 15× and 41× lower query cost compared to Zilliz and Pinecone serverless enterprise products." It can further scale to billions of vectors with automatic partitioning.

If you're going to Microsoft #MSBuild come learn how to build multi-agent apps using Semantic Kernel in C# or #LangGraph in Python at our hands-on-lab. build.microsoft.com/en-US/sessions… There's another earlier delivery as well.

Ep. 104 of #AzureCosmosDB TV is here! 🎥 High-Scale Data Processing over 1000s of Devices with Expanso. @markjbrown @aronchick See how @ExpansoIO + Azure Cosmos DB handle 50M records in under a minute with 1,000 edge nodes 🌍 youtu.be/F2VMVjSxIHY #EdgeComputing #DistributedSystems #NoSQL
