Dec 1, 2025December 2025 monthly summary for Planning-Inspectorate/odw-synapse-workspace focused on governance, deployment efficiency, and reliable notebook workflows. Key features delivered include JSON-driven AutoResolveIntegrationRuntime and default managed VNet configurations in Synapse workspace, enabling streamlined connectivity and security posture. A publishing/deployment configuration framework was established via new publish_config.json (and updates for targeted branches and Git comment options), improving release consistency and traceability. Implemented classification-driven data anonymisation with Azure Purview integration, including masking rules, Purview-based classifications traversal, logging, and tests to enhance data privacy controls. Reverted nsip invoice table changes to stabilize the harmonised database and reduce accidental data model drift. Performance/stability improvements were made to the dart_api curated notebook by removing Z-ORDER, clustering at write time, and persisting DataFrames to cut timeouts. Notebook observability and parameterization were enhanced with logging/telemetry in create_table_from_schema and added pipeline parameters for pln_service_bus workflows. Overall impact includes stronger data governance, safer data handling, faster release cycles, and more observable, maintainable notebook-based pipelines.
