K-Core decomposition
Describe the solution you would like
"A distributed k-core decomposition algorithm on spark"
k-core decomposition of a graph is a popular graph analysis method that has found widespread applications in various tasks. Thanks to its linear time complexity, k-core decomposition method is scalable to large real-life networks as long as the input graph fits in the main memory. For graphs that do not fit in the main memory, external memory based approach or distributed solution based on iterative MapReduce platform have been proposed. However, both external memory solution and iterative MapReduce based solution are slow due to their high disk I/O cost. In this paper we propose, Spark-kCore, a distributed k-core decomposition algorithm, which runs on Spark cluster computing platform. Using think-like-a-vertex paradigm, the proposed method utilizes a message passing paradigm for solving k-core decomposition, thus reducing the I/O cost substantially. Experiments on 15 large real-life networks show that our method is much faster than the existing k-core decomposition solutions.
