1. Unified Lakehouse Architecture with a Bounded AI Analytics Agent

InfoQ (Leela Kumili). Cloudflare detailed Town Lake, a lakehouse platform built on Apache Trino, Apache Iceberg, R2 object storage, and DataHub that lets a single query join data across Postgres, ClickHouse, and Iceberg tables without moving it between systems, then layered on Skipper, an AI analytics agent that translates natural language requests into SQL using catalog metadata and schema definitions. The design pairs the agent with a default-closed governance model, where new datasets stay inaccessible until automated classification and human review complete, so the agent’s action surface stays bounded even as it serves billing, support, and security workflows. Independent commentary in the piece argues that adding an AI agent atop unified analytics requires enforcement to sit close to execution through distributed deterministic checks, a reusable pattern for practitioners granting agents broad read access to production data.
