Richard Gankema is a Computer Scientist at RelationalAI, working on various systems-related topics such as data structures, memory management and query execution. Before joining RelationalAI he worked as a PhD candidate at CWI’s Database Architectures group in Amsterdam, which sparked his interest in vectorization and other techniques for optimizing the performance of data-processing.

Modern databases can choose between two approaches to evaluating queries with high performance: Query Compilation compiles each query to optimized machine code, while Vectorization interprets queries using BLAS-style primitives.
Query compilation offers more optimization potential for LLVM, while vectorization doesn’t require runtime compilation.
We explain how these techniques work and how we combine them, showcasing how Julia lets us have the best of both.
