Topics include data partitioning and replication across availability zones using multi-Paxos consensus, leader election, write-ahead logging, and the metadata service architecture. The explanation covers how DynamoDB uses a distributed in-memory store (MemDS) with local router caching to avoid cascading failures, storage admission control via token buckets, read/write capacity units, and the throughput dilution problem that arises when hot partitions are split. Real-world scale numbers from Amazon Prime Day 2021 (89.2M requests/second) are used to illustrate the system's capabilities. ## Full article daily.dev links to this article rather than hosting it.
