February 2026 monthly summary for ClickHouse/clickhouse-docs focusing on ChDB datastore documentation and performance mode. Delivered comprehensive, developer-facing docs for chDB v4 datastore, including configuration, accessors, aggregation functions, and I/O operations, with guidance on lazy evaluation and SQL optimization. Introduced a dedicated performance mode section to articulate benefits, usage patterns, and trade-offs. Improved overall clarity, accuracy, and structure of the datastore docs.

December 2024 highlights for ClickBench (ClickHouse/ClickBench repository). Key deliverable: benchmark suite updated to align with chdb 2.2.0b1, including updated benchmark scripts and library version bumps, timing adjustments in query.py for dataframe normalization and per-query metrics, and output filename tweaks to reflect machine configurations. Impact: improved accuracy and comparability of performance metrics across configurations, enabling more reliable performance assessments and business decisions. Bugs: no critical bugs fixed this month; minor metric drift addressed via timing normalization improvements. Technologies demonstrated: Python benchmarking tooling, library version management, data normalization techniques, per-query timing instrumentation, and configuration-aware output reporting. This work strengthens data-driven decision making and supports clear performance SLAs for product teams.

Monthly summary for 2024-11 focused on delivering reliable benchmark tooling improvements and optimized query execution paths for the ClickBench project (ClickHouse/ClickBench). The changes emphasize stability, reproducibility, and business value through dependency stabilization, code cleanup, and performance-oriented refactoring.
