January 2026 summary: Stabilized the Databricks Terraform provider in the face of API deprecation by implementing a resilient fallback for data_source_id. The fix ensures that databricks_sql_warehouse and databricks_sql_endpoint return an empty string when the data source API call fails, preventing breakages during API deprecation and future removals. The change enhances reliability for customer automation and CI pipelines that rely on Terraform configurations. Key outcomes: - Key features delivered: fallback for data_source_id on API failure for two resources; avoids provider breakage due to deprecated API. - Major bugs fixed: API failure path no longer propagates as a crash; data_source_id gracefully defaults to empty string. - Tests and validation: unit tests using Go SDK and TF Plugin Framework; local make test; docs updated; NEXT_CHANGELOG.md entry. - Documentation and awareness: updated docs/ to reflect behavior; changelog prepared for release notes. Overall impact and accomplishments: - Maintains compatibility with deprecated API, reducing customer downtime and manual remediation. - Improves stability of databricks_sql_warehouse and databricks_sql_endpoint in automation pipelines. - Demonstrates strong resilience engineering by handling API deprecation gracefully while preserving existing workflows. Technologies/skills demonstrated: - Go SDK, Terraform Plugin Framework, unit testing, documentation discipline, changelog maintenance, and CI-aligned validation.
