DuckDB’s Vectorized Execution Boosts Speed by Batching 2,048 Rows
DuckDB processes data in cache‑friendly vectors of 2,048 rows, letting it apply pre‑compiled operators across the batch with a single selection vector. This push‑based pipeline slashes copying and improves CPU IPC, turning per‑row Volcano execution into a high‑throughput, columnar engine that runs queries dramatically faster.
