MagnetoDB is Amazon DynamoDB API for OpenStack world.

Why it is needed?

To provide hight level database service with DynamoDB API interface

Why not Trove?

Initially suggested as blueprint for Trove it was rejected as not following the programm mission. MagnetoDB is not one of existing database provisioned by Trove, but storage with HTTP API where Trove is used for provisioning and managing underlaying database.

Overall architecture

It two layer horizintally scalable web application

API

The API consists of the following methods

Implementation

Pluggability

The most suitable data source is Cassandra. But it is better to make datasource plugguble and give the framework for implementation of interface for any other underlying storage.

OpenStack component reusage

Purpose	OS component
Provisioning of web tire	Heat, Mistral (Convection)
Load balancer	LBaaS, Neutron
Autoscaling of web tier	Heat autoscaling, Ceilometer
Data Source provisioning and management	Trove
Monitoring	Ceilometer
Authentication	Keystone

Autoscaling

Web autoscaling is suggested to implement with HEAT autoscaling group resource
Datasource scalability based on future Trove autoscaling
