Program
Dive into the new features of Cosmos DB 2026 with a focus on dynamic partitioning and vector indexes, applied to preparing datasets for D3.js. Perform practical exercises on modeling complex graphs, test RU/s performance in massive data visualization scenarios, build your first optimized container model for interactive dashboards, analyze live latency metrics, and validate production-ready deliverables via Azure Portal.
Explore the SQL and MongoDB APIs of Cosmos DB 2026 coupled with D3.js for dynamic visualizations, implement real-time change feeds to update live dashboards. Practice vector queries on large datasets, integrate JavaScript hooks for smooth rendering, simulate IoT streams with reactive data visualization, measure performance gains, and produce a fully functional multi-source dashboard prototype.
Master RU autoscaling and distributed caching in Cosmos DB 2026 for high-load dashboards, apply advanced sharding strategies with D3.js. Test extreme data visualization workloads, optimize costs via built-in analyzers, implement multi-region setups for zero latency, benchmark against competitors, debug bottlenecks in groups, and deploy a scalable deliverable supporting 1M+ data points.
Configure granular RBAC and VNet integrations in Cosmos DB 2026 to secure critical data visualization flows, link to ETL tools like Azure Synapse for enriched dashboards. Develop secure pipelines with client-side encryption, simulate GDPR-compliant audits, integrate D3.js with Azure AD auth, test vector injections, and finalize an end-to-end pipeline with integrated monitoring and automated reports.
