Worked on the apache/doris repository, focusing on backend development, data loading, and testing to enhance reliability and maintainability across core workflows. Delivered features such as storage vault upgrade testing, Kafka routine load stabilization, and comprehensive DDL test coverage, using Java, Groovy, and SQL to implement robust validation and regression tests. Improved deployment consistency by migrating Docker Compose configurations to internal images and expanded test automation for Docker-based routine load scenarios. Addressed data correctness in Merge-on-Write paths and streamlined TVF error data testing by removing duplicates, resulting in reduced CI noise and faster feedback cycles for ongoing development.

Sep 1, 2025September 2025 — Apache Doris: Strengthened DDL reliability by adding Load DDL Testing Coverage across all data-loading paths (stream load, routine load, and S3 load). Implemented new test cases validating diverse mapping scenarios to ensure robustness and correctness of DDL operations. The change improves regression coverage and reduces risk associated with schema changes and data ingestion. Primary commit contributing to this work: 23acc85a58a84ea00895d1a1f6a115a4069fd46d.

Jul 1, 2025July 2025 performance summary for apache/doris focused on stabilizing Kafka Routine Load tests to improve reliability and CI feedback. Delivered a feature-level improvement that validates Kafka connections before use and configures producer timeouts to prevent hangs, reducing flaky test runs and accelerating validation of ingestion workflows. This work aligns testing behavior with production expectations and lays groundwork for more robust data ingestion via Routine Load.

Nov 1, 2024November 2024 monthly summary for apache/doris: Delivered upgrade-testing enhancements for storage vault. Refactored tests by moving storage vault creation tests from test_create_vault.groovy to a new load.groovy, enabling better adaptation for upgrade scenarios and improving coverage of vault creation/usage during system upgrades. This reduces upgrade risk and shortens feedback cycles.
