Mar 1, 2026

March 2026 (datahub-project/datahub). Focused on improving Teradata ingestion usability and correctness. Delivered a targeted feature to initialize Teradata database context for metadata ingestion, ensuring that view processing and metadata ingestion work without requiring an explicit database in the connection string. This reduces user configuration friction and prevents ingestion errors caused by missing DB context. Change tracked in commit 62459feab491e65a44b5345cf006555e53e07e3a (fix(ingest/teradata): set DATABASE context for view HELP commands, #16208). Overall, the update strengthens the Teradata ingestion path, enhances reliability, and smooths onboarding for Teradata-backed metadata workflows.
