CobbleDB's write path: state, delivery, and serving split across Pillar, Lorry, and CobbleDB

Perplexity explains how updates reach CobbleDB: durable document state, update delivery, and serving are separated across Pillar, Lorry, and CobbleDB. Pillar stores versioned document state in YTsaurus and queues exports; Lorry writes partitioned S3 batches that replicas apply independently and in order, so recovering nodes don't delay others and each replica ingests at its own pace.
