Zhang Minke contributed to the apache/doris repository by building and stabilizing core backend features and regression tests that improved system reliability and operational visibility. Over seven months, Zhang integrated MinIO cloud storage, enhanced audit logging, and expanded metrics for data distribution, using Java, Shell scripting, and SQL. He addressed test flakiness by refining regression suites, introducing unique resource naming, and strengthening error handling for audit logs and broker-load pathways. His work included developing Groovy-based job scheduling documentation and automating test infrastructure, resulting in more deterministic CI pipelines and safer releases. The engineering demonstrated depth in distributed systems and database internals.

Jul 1, 2025In 2025-07, delivered targeted regression-test fixes for the apache/doris repo, focusing on audit log reliability and broker-load correctness. The Audit Log Regression Test Stabilization and Schema Adaptation fixes improved test reliability across environments by tightening schema changes, adjusting expectations for audit log handling, updating test scripts for SQL length behavior, and enforcing explicit failures when tests encounter repeated query failures or HDFS-disabled environments. The Broker Load Regression Test Fix corrected expected outputs, updated documentation, and used the correct SQL command for S3-related operations, ensuring accurate regression coverage for broker-load pathways. These changes reduce test flakiness, strengthen CI stability, and increase confidence in production behaviors for audit logs and data ingestion. Technologies demonstrated include regression testing, test automation, schema evolution handling, environment-aware testing, and robust error signaling.

Jun 1, 2025June 2025 monthly summary for apache/doris. Key features delivered: Flaky test mitigation for Cold Data Compaction by relocating test to nonConcurrent suite, adjusting timeouts and disable_auto_compaction handling to improve reliability. Major bugs fixed: Reduced flaky behavior in Cold Data Compaction tests, increasing CI determinism. Overall impact: Improved reliability and maintainability of the regression suite for critical data-path tests, enabling faster feedback and safer releases. Technologies/skills demonstrated: regression testing discipline, CI/test harness tuning, test suite rearchitecture, and commit-based traceability.

Feb 1, 2025February 2025 monthly summary for apache/doris focused on enabling MinIO Virtual Host Style access for storage vaults and strengthening test coverage. Delivered regression tests and configuration to support MinIO's Virtual Host Style (domain-based host-style) access, enabling compatibility with both S3 path-style and virtual host-style accesses. This work reduces integration friction for MinIO-based deployments and sets the stage for broader compatibility across storage backends.
