== What is MagnetoDB? ==

'''MagnetoDB''' is a key-value store service for OpenStack. It provides horizontally scalable, queryable storage, accessible via REST API. MagnetoDB supports Amazon DynamoDB API as well. MagnetoDB has been designed and developed in order to provide:
−
MagnetoDB is [http://aws.amazon.com/dynamodb Amazon DynamoDB] [http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/API.html API] for OpenStack world.
+
* ''Easy integration'': REST API. Support Amazon DynamoDB API
−
=== Why it is needed? ===
+
* ''OpenStack interoperability'': integrated with Keystone. Follows OpenStack design tenets, packaging and distribution
−
To provide hight level database service with DynamoDB API interface
+
* ''Database pluggability'': supports Cassandra,any other databases like MongoDB, HBase could be easily added
−
=== Why not Trove? ===
+
* ''Horizontal scalability'': MagnetoDB is scalable lineary by amount of data and requests
−
Initially suggested as [https://blueprints.launchpad.net/trove/+spec/http-accessible-storage blueprint] for Trove  it was rejected as not following the programm mission.
+
* ''High availability'': just one working API node is enough to continue handling requests
−
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.
