ExtendDB – The DynamoDB API, everywhere you run code
ExtendDB is an open-source adapter that allows users to run DynamoDB workloads on their own infrastructure. It translates API requests from DynamoDB clients to various pluggable storage backends, such as PostgreSQL and Cassandra. This solution enables local development, integration testing, and deployment in environments without cloud connectivity.
- ▪ExtendDB is compatible with the DynamoDB wire protocol and can be used with any DynamoDB SDK.
- ▪It supports multiple storage backends, including PostgreSQL as the reference backend and Apache Cassandra.
- ▪ExtendDB is released under the Apache 2.0 license, allowing for modification and redistribution.

Endpoint configuration is the only change.
