All numbers on one machine and environment, attributed in the docs: Apple M2 Pro, ClickHouse 25.12.11.4 in Docker, Python 3.11.11. Methodology change: scripts end their imports with 'import timing' (new perf/timing.py) which starts the clock and reports wall time and max RSS at exit. Interpreter startup and imports are excluded from timings; importing the numpy/pyarrow stack costs ~0.5 s and dominated sub-second cells under whole-process timing. New typed-projection PyArrow scripts (21-24) cover analytic extracts: int and string column subsets, clickhouse-driver vs clickhouse-connect. All perf scripts carry PEP 723 blocks with pinned versions. Scripts 15-17 updated to the current clickhouse-connect streaming API. beep boop
