Contributed to the apache/druid repository by building features that enhance query management, reliability, and data governance. Developed dynamic broker configuration and a runtime query blocklist, enabling operational agility and improved cluster security without requiring restarts. Implemented per-segment timeout configuration per datasource, allowing tailored query responsiveness for heterogeneous workloads. Strengthened SQL query input validation and error handling to improve diagnostics and user experience. Delivered an OpenLineage data lineage extension, leveraging Java, TypeScript, and SQL parsing to capture end-to-end lineage for Druid queries. Work demonstrated depth in backend development, API integration, and extension design, supporting observability and compliance for data pipelines.

Jun 1, 2026June 2026: Delivered OpenLineage data lineage extension for Apache Druid queries, enabling end-to-end data lineage capture and governance. Implemented Calcite-based SQL parsing to extract inputs and outputs for lineage events, and extended native queries with correct table-name discovery. Emitted rich OpenLineage events using a contrib extension (openlineage-emitter) with both standard OpenLineage facets and custom Druid-specific facets. This work enhances observability, impact analysis, and debugging capabilities for data pipelines, supporting governance and compliance efforts. Demonstrated strong capabilities in extension development, SQL parsing, and API integration for lineage data.

Apr 1, 2026April 2026 monthly summary for apache/druid: Implemented per-segment timeout configuration per datasource to tailor timeout thresholds for different datasources, improving query management and responsiveness for heterogeneous workloads. Updated the dynamic configuration API and related BrokerDynamicConfig classes to support per-datasource per-segment timeouts. This change is tied to commit 9157bdd6f254135c094255db8822c806537b9eb9 (feat: Segment Timeout Per Datasource) and lays groundwork for more granular resource governance and SLA adherence.

Feb 1, 2026February 2026 monthly summary for apache/druid: Focused on strengthening SQL query input validation and error handling to improve reliability, user experience, and diagnostics. Delivered a targeted bug fix that classifies user errors, ensuring invalid inputs return the 400 (USER/INVALID_INPUT) code rather than 500, reducing support overhead and enabling faster triage.
