DynamoDB ORM for Node.js
A DynamoDB ORM for Node.js
It aims to provide a few added features that most people will want from a DynamoDB tool. These things include a Mongoose inspired way of doing things, periodic S3 backups, multi-indexing (clones data to seperate tables, having different indexes on each) and more.
For now it provides a simple way to interact with DynamoDB and create/read rows in the table. More features coming.

- Periodic (user defined time) backups to S3
- Multi-indexing to allow one data type to be indexed via multiple keys (we'll use DynamoDB's strong consistency and data replication here)
- Elastic Map Reduce (so you can run SQL like queries over the data sets you store)
A big thanks go out to Jed Schmidt and other contributors for dynamo which sits as an API abstraction for DynamoDB that made this process significantly easier.
Another big thanks go out to all the contributors of mongoose as it was a huge inspiration to the design of how users interact with the project.
