Dec 1, 2025

December 2025: Delivered a key feature in the StreamNative Terraform provider that enables lakehouse storage by default for serverless Pulsar clusters. The lakehouse_storage_enabled attribute is now computed and always true, and cannot be overridden by users on serverless instances. This change improves reliability and user experience by preventing misconfigurations and ensuring consistent behavior across deployments. No major bugs fixed this month. Overall impact: higher stability for serverless deployments, simplified operator workflows, and clearer expectations for storage behavior. Technologies demonstrated: Terraform provider development, computed attributes, defaulting/enforcement logic, and clear change governance via PRs in the Go/Terraform ecosystem.
