Perplexity built CobbleDB, a Rust key-value store, with help from hundreds of coding agents to reduce DynamoDB costs and improve read latency for search traffic. The company reports lower median and tail latency and expects at least 20% lower costs, but human engineers retained control of the architecture and production system.
