Wasm Threads and SIMD

How WebAssembly's threads proposal (shared memory and atomics) and fixed-width SIMD unlock parallel and data-level performance for compute-heavy workloads.

What is Vectorized Query Execution?

Vectorized query execution processes data in batches of many values at once, using CPU SIMD instructions and cache-friendly columnar layouts, instead of the tr…
