Monthly work summary for August 2025 focused on stabilizing cloud-mode time-series compaction testing in Apache Doris. Delivered a targeted test fix to ensure correctness and reliability in cloud environments, enabling accurate compaction status updates and reducing CI flakiness.

Month: 2024-12 — Apache Doris (repo: apache/doris) Overview: - Principal focus this month was improving regression test reliability and maintainability by centralizing compaction operations under a single API, enabling faster feedback loops and reduced test duplication. Business value: - Stabilizes regression tests around various compaction scenarios, reducing flaky tests and accelerating release readiness. Technologies and practices demonstrated: - Test automation design (unified trigger_and_wait_compaction), API simplification, and regression test engineering. - Git-based collaboration and traceability through explicit commit reference. Notes on deliverables and impact: - Implemented a centralized method to trigger and wait for compaction across multiple operations in regression tests, lowering maintenance and enabling broader test coverage. - This work directly supports Doris reliability in CI pipelines and aids developer productivity by providing a single, reusable test utility.
