The aim of the project is to integrate graph databases as inputs for Giraph, along with the current ones (e.g. HBase, Accumulo etc.). In particular, use Tinkerpop with Giraph as a way to inject data into Giraph for graph analytics. Precisely, to leverage Blueprints and Rexter, that build a vendor-agnostic API over the vendor-specific ones, and export it via a REST API.

Project Scope

The project scope is divided in three main milestones:

• Integrate Rexter into Giraph inputs, e.g. leveraging existing classes in Faunus for MapReduce
• Define a mapping between the flexible Property Graph data model to Giraph's data model
• Allow to specify the input graph from the graph database to Giraph via a query (not only support injecting the whole graph)

For very successful students, there are possibilities to extend the work with more deliverables:

• Support Titan as an input
• Support GraphSON as an InputFormat
