Open-source DynamoDB-compatible adapter with pluggable backends, directly relevant to cloud infrastructure and data engineering.
Summary
AWS open-sourced ExtendDB, a Rust-based DynamoDB-compatible adapter that translates the DynamoDB wire protocol to SQL, enabling PostgreSQL as a pluggable storage backend. Currently at version 0.1, it supports core DynamoDB APIs (tables, items, streams) and runs as a single binary with SigV4 auth, targeting local dev, CI, and on-premises workloads. Early benchmarks show high write latency (300ms p90 at concurrency 10), but the pluggable storage trait allows future backends like Cassandra or MySQL.
