meng shao (@shao__meng): Deep dive into CobbleDB: Why Perplexity rewrote the storage layer for AI search
@perplexity_ai replaced DynamoDB with a three-tier stack consisting of a hot storage layer (CobbleDB) + a persistent state layer (Pillar) + a batch delivery layer (Lorry), reducing batch write latency by approximately 5× and costs by at least 20%. This system, composed of about 40,000 lines of Rust code, was built by just 2 engineers alongside hundreds of AI coding
