Giraph Algorithmic Building Blocks

This chapter covers

  • Principles and patterns behind scalable graph algorithms
  • Graph connectivity, paths, and connected components
  • Ranking vertices with PageRank
  • Predicting ratings for user-item recommendations
  • Identifying communities with label propagation
  • Graph types and how to characterize them

This chapter focuses on algorithmic building blocks for graph algorithms, with a particular emphasis on their scalability. Graph problems are commonly solved in Giraph using a number of patterns. Due to Giraph’s vertex-centric paradigm based on message-passing, patterns use a type of value propagation. The ...
