During August 2025, Lizi Zhang enhanced backend performance for the kestra-io/kestra repository by optimizing paginated data retrieval. She replaced SQL_CALC_FOUND_ROWS with COUNT(*) across repository classes, reducing database load and improving the speed of total-row computations for UI and listing operations. This change, implemented in Java and SQL, focused on SQL optimization and database performance tuning, resulting in faster and more scalable queries under large datasets. Lizi’s work demonstrated a methodical approach to repository refactoring, with clear changelist traceability. Although no bugs were fixed during this period, her contribution addressed a core performance bottleneck with measurable business value.
