Subject [jira] [Commented] (AIRAVATA-341) [GSOC] NoSQL implementation for Airavata Registry
Date Wed, 29 Jan 2014 21:04:10 GMT

Nipun Udara commented on AIRAVATA-341:
--------------------------------------

I am interested about this project and According to What i understood so far, Airavata registry
is a common component used  by Xbaya , GFac , Orchestrator to store and retrieve data  such
as service information, workflow metadata and workflow consumed input and generated outputs.
The Airavata specific registry API is build over the generic JCR API layer which is used to
store/retrieve data from the Jackrabbit content repository.

The goal of this project is to replace the jackrabbit implementation with NoSql implementation
such as Cassandra which can provide linear, scalable , large profile database which can handle
high volume of simultaneous read/write requests without running into table locking while preserving
the currently supporting feathers of the Airavata registry.

I would be grateful if you can clarify more about the requirements of this project.

> Airavata's Registry is used to store and retrieve services and workflows. The Registry
is currently very lightweight with an implementation based on Apache Jackrabbit. This task
is to develop a more powerful registry capable of handling a wider variety of use cases and
science gateway metadata.  Issues include development of JSON metadata models for different
use cases, development and evaluation of metadata search capabilities (both expressiveness
and performance), and development and evaluation of access policies for the metadata.  The
latter may involve integration with Apache Rave as an OpenSocial engine for defining groups
and filtering requests.  
> Evaluating the capabilities of multiple NoSQL databases will be an important component
of this task. Candidate technologies from Apache include Cassandra and CouchDB, but appropriately
licensed non-Apache projects such as MongoDB will also be evaluated. 
> Sample use case scenarios will include computational chemistry, material science, astronomy,
and earth science.
