It supports existing AWS SDKs and tools without modification, runs as a single binary with TLS and SigV4 authentication, and uses a pluggable Rust trait-based storage layer that can accommodate additional backends like Cassandra or MySQL. Primary use cases include local development, CI testing, and on-premises DynamoDB-style workloads. Early community feedback notes performance concerns under high write load, and a similar independent project called Rektifier also exists. The project is available on GitHub under Apache-2.0. ## Full article daily.dev links to this article rather than hosting it.
