Concise monthly performance summary for Apache Doris (May 2025). Focused on cloud mode reliability and test harness robustness to support cloud deployments and reduce CI flakiness.

February 2025: Strengthened Doris multi-cloud regression testing and cache hotspot validation, delivering tangible business value through more robust cross-cloud behavior and reliable hotspot detection. Key work included: 1) cross-cloud regression test enhancements for Azure by adding a PROVIDER property to S3 test configurations and broadening error URL assertions to cover error_log, 2) a new Groovy-based cloud file cache hotspot test and updates to existing tests for resilient hotspot validation across compute groups and tables, and 3) a bug fix to the cache hotspot detection logic ensuring accurate hotspot reporting. These changes reduce flaky test outcomes, accelerate safe deployments across cloud providers, and demonstrate proficiency in test automation, Groovy scripting, and regression testing workflows.

January 2025 monthly summary for apache/doris: focus on improving authorization reliability by addressing edge cases in GRANT statements. Implemented backtick quoting for cluster names that contain keywords or special characters to prevent GRANT-time syntax failures across test files, ensuring consistent access control behavior. Result: more reliable authorization, fewer test-time failures, and reduced manual debugging.
