PROFILE

Mihai103

Contributed to the acrylidata/datahub repository by delivering features and fixes that enhanced data governance, ingestion reliability, and user experience. Developed project-based asset filtering for Tableau data source ingestion, using Python and ETL skills to improve governance and observability. Addressed schema conversion challenges by implementing cycle-safe AVRO-to-DataHub transformations, leveraging Java and data modeling expertise. Extended CLI upsert functionality to support dataset-domain associations, enabling domain-based governance policies. Improved UI feedback by surfacing test status in health icons on entity pages with React and GraphQL. Also resolved backward compatibility issues in Java, ensuring safer data processing and reducing runtime errors in ingestion workflows.

January 2026 (2026-01) focused on stabilizing data ingestion paths and improving backward compatibility in the datahub repository. A targeted bug fix addressed null extraFields handling and data product reading with the output_port path, resulting in safer data processing for older Java versions and reduced risk of NPEs. The change was reviewed and co-authored by Mihai Ciocirdel and Deepak Garg, reflecting effective collaboration.

July 2025: Implemented Dataset Domain Association in Upsert via CLI for acryldata/datahub, extending the Dataset model with a domains field and generating MetadataChangeProposals to map datasets to domains. Added end-to-end tests and a YAML configuration to enable governance-driven dataset-domain relationships. This work enhances data governance, lineage, and domain-based access policies, enabling improved data discoverability and policy enforcement. No major regressions reported; prepared for broader domain mappings and rollout.

February 2025: Delivered focused data ingestion improvements for acrylidata/datahub, prioritizing governance, observability, and stability in Tableau data source ingestion. Implemented project-based asset filtering to skip assets associated with filtered projects, enhanced visibility with warning logs for skipped assets, and expanded test coverage with an integration test validating project-path-based filtering. The changes reduce unnecessary data processing, improve data quality, and reinforce governance controls across ingestion workflows.
