Summary from the TLDR Data newsletter

Meta rebuilt its ads ML feature infrastructure to deploy features independently without losing the efficiency of shared computation. F3 Lightning uses stable computation IDs, a unified execution plan, and shared memory to avoid redundant processing across more than 20,000 features. Comparable features now reach production 3.6x faster without increasing infrastructure compute costs.
