Tim's Corner: Summit Week Countdown - AI Function Studio, Iceberg Writes GA, and Batch Search

Welcome to issue 243! Snowflake Summit 2026 is ONE WEEK away - I'll be speaking on NiFi and Agents in San Francisco June 2. This week Snowflake shipped a wave of GA releases leading into Summit. Cortex AI Function Studio entered public preview - create, evaluate, and optimize production-ready AI Functions with automated prompt engineering and model selection. Iceberg table writes via external query engines went GA through Horizon Catalog - read AND write to Snowflake-managed Iceberg v2/v3 tables from Spark or any Iceberg REST engine. Batch Cortex Search went GA with the CORTEX_SEARCH_BATCH table function for millions of fuzzy-match queries in a single SQL statement. Storage lifecycle policies for dynamic tables went GA. dbt Projects on Snowflake got enhanced DAG visualization with column-level lineage. CREATE OR ALTER SEMANTIC VIEW entered preview for declarative semantic view management. The dynamic tables documentation got a full 30-page rewrite. dbt Fusion is now available on Snowflake. And MCP now connects GitHub Copilot in VS Code to Snowflake Cortex Agents. OpenFlow keeps expanding with SQL Server CDC, Amazon Kinesis streaming, and more. See you at Summit!
