iMapReduce: A Distributed Computing Framework for Iterative Computation

Relational data are pervasive in many applications such as data mining or social network analysis. These relational data are typically massive containing at least millions or hundreds of millions of relations. This poses demand for the design of distributed computing frameworks for processing these data on a large cluster. MapReduce is an example of such a framework. However, many relational data based applications typically require parsing the relational data iteratively and need to operate on these data through many iterations. MapReduce lacks built-in support for the iterative process.
