In their own words
Amazon DynamoDB
Amazon DynamoDB is a serverless, managed NoSQL database for applications that need single-digit millisecond performance at any scale, according to AWS. Users do not provision or patch database servers, and tables can scale automatically, including to zero in on-demand mode. Primary keys and global or local secondary indexes provide ways to query data. Global tables support multi-Region, multi-active operation; AWS says they are designed for up to 99.999% availability. The database also supports native vector search for similarity searches and agent memory use cases. Data is encrypted in transit and at rest by default, and IAM policies can restrict access to specific items and attributes. Point-in-time recovery provides continuous, per-second backups and restoration within a configured period of 1 to 35 days. A free tier is listed with 25 WCUs, 25 RCUs, and 25 GB of storage per Region and payer account, among other limits. On-demand capacity is billed per request consumed; provisioned capacity is billed for specified capacity even if usage is lower.
TiKV
TiKV is a distributed transactional key-value database designed as a unified storage layer across nodes. It provides a raw key-value API and a transactional key-value API with ACID semantics, but those APIs cannot both be used on the same keyspace. The project says it can support petabyte-scale deployments spanning trillions of rows. Raft groups replicate data across nodes for fault tolerance, while horizontal scaling and rebalancing support changes in cluster capacity. RawKV also includes time-to-live expiration and compare-and-swap operations. The documentation lists Java, Go, Rust, Python, and C++ clients; Java and Go are marked stable, while the others are marked unstable. TiKV is self-hosted and Apache 2.0 licensed, with Linux, macOS, Windows, and API listed as platforms. Its documentation describes TLS for network connections and configurable encryption at rest, including AES methods. TiKV was originally created by PingCAP and is a Cloud Native Computing Foundation graduate project. The community page recommends Slack for general communication and provides a dedicated mailing list for security vulnerability reports.
