ExtendDB: Open Source Amazon DynamoDB Compatible Adapter with Pluggable Storage Backends
AWS recently announced ExtendDB, a DynamoDB-compatible adapter that lets developers use the DynamoDB API with different storage backends, starting with PostgreSQL. The project supports existing SDKs and tools without modification, giving teams greater flexibility to run DynamoDB-style workloads outside of native DynamoDB while maintaining compatibility with current applications and workflows.

The proliferation of cloud-native applications and the desire for vendor lock-in avoidance have made flexible database tooling increasingly relevant, and AWS is responding to this demand.
This development allows organizations to leverage DynamoDB's API and application ecosystem on alternative, potentially self-managed or more cost-effective backends, increasing flexibility and reducing dependency on AWS's proprietary service.
Developers can now use familiar DynamoDB APIs with non-DynamoDB storage, potentially shifting database strategy to hybrid or multi-cloud environments without re-architecting applications.
