January 2026 monthly summary for datahub-project/datahub. Delivered a set of cross-functional enhancements and reliability improvements that expand data ingestion, metadata extraction, and platform integration while improving performance and developer productivity. Notable deliverables include the Microsoft Fabric OneLake Connector for end-to-end metadata extraction across workspaces, lakehouses, warehouses, schemas, and tables with multi-auth support and SQL Analytics Endpoint-based schema extraction. In PowerBI, dataset/workspace key generation was enhanced to incorporate platform instance and environment, enabling stable GUIDs for stateful ingestion. An ingestion recording and replay system was implemented to capture HTTP requests and database queries for offline debugging. A new validation step ensures all plugin dependencies are installed before metadata ingestion, reducing runtime failures. SQL aggregator received performance improvements and testing, including micro-optimizations and an option to skip join processing for faster queries. Databricks integration was stabilized by adding the missing databricks-sdk dependency and addressing authentication issues in the SQL connector. Additional reliability improvements included preventing duplication of platform instances in browse paths.
