Tim's Corner: ArcticSwarm, Virtual Columns, Composable Semantic Views, and NiFi Security

Welcome to issue 249! This week brings a parade of post-Summit innovation. Snowflake engineering published on ArcticSwarm - a multi-agent system architecture for orchestrating AI agents at scale. Virtual Columns landed as an engineering deep dive on eliminating redundant storage. Composable Semantic Views entered limited access for modular semantic model design. Analytical Search entered public preview. Claude Sonnet 5 is now on Cortex AI. Snowflake Cowork launched as a personal work agent. Workload Identity Federation for external services went GA. Three Semantic View releases dropped: sample values, variables, and inline view GA. On the Apache side, NiFi 2 security enhancements and Flink Agents 0.3.0 shipped. The community delivered a comprehensive Summit feature summary, CI/CD with DCM Projects, Schemachange + Snowflake CLI, and a self-healing demo. I published three new repos - YOLOCamera, CoCoTracking, and SecurityWorkshop. Let's dig in!
