MagnetoDB is an open source implementation of the Amazon DynamoDB API for OpenStack. It provides a key-value database service for storing unlimited data with scalability and predictable performance. MagnetoDB's API is compatible with existing DynamoDB clients, allowing applications using DynamoDB storage to run on OpenStack. The pilot implementation provides basic CRUD operations for items and tables and is available on GitHub under an Apache 2 license.
