Pasindu Gunarathne commented on NUVEM-9:
----------------------------------------

 Apache Nuvem defines an open API which abstracts common cloud platform 
services to help decouple the application logic from the particulars of a 
specific proprietary cloud. Nuvem initially  supported Google App Engine, 
Amazon EC2 and Microsoft Azure cloud platforms also provided some standalone 
services for some features so that the users can move among different cloud  
platforms or use standalone service provided by Nuvem itself. 


Highly scalable and distributed structured key-value data services are an 
essential feature for today's enterprise applications. Majority of  cloud 
service providers such as Google , Amazon provide key-value data services and 
also there are number of standalone  key-value databases available. Apache 
Cassandra  and Apache HBase are some of the them. 

Supporting the key-value data services is a very important item listed in Nuvem 
road map which will be the key deliverable of this proposal. This high level 
goal can be further broken down in to sub tasks as follows. 


1.) Define the API for Nuvem key-value data services. 

2.) Implement Nuvem key-value data services API based on Google App Engine SDK 
and provide test cases for this implementation. 

3.) Implement Nuvem key-value data services API based on Amazon SimpleDB SDK 
and provide test cases for this implementation. 

4.) Implement Nuvem key-value data services API based on standalone key-value 
databases. 

At the moment Apache Cassandra  and Apache HBase identified as possible 
candidates but final decision will make after  having discussion within the 
community.  


5.) Sample applications to demonstrate the use of Nuvem key-value data services 
API  , Provided user and configurations guide for this feature.
