What is a 'Vectorized Query Engine'?

Approach: Explain processing data in batches of values rather than row-by-row.

An engine that processes multiple rows of data at once using batches (vectors) instead of one row at a time. It leverages CPU SIMD instructions for massive performance gains.

Follow-up: Name a database that uses vectorization.

Key concepts: simd, cpu cache, batch processing.
