Redis creator antirez shares the four-month development of the Array data type, significantly accelerated by LLMs (Opus for specification, then GPT-5.3/Codex for system programming). The AI tools enabled rapid iteration on architectural trade-offs and code generation while human review remained constant. The feature includes sparse array representation and efficient two-level indirection for large allocations.
