Sixth TUC Meeting: Lighthouse - Large-scale graph pattern matching on Giraph by Claudio Martella (VUA)
To end the first day slot of the morning presentations during last 6th TUC Meeting in Barcelona Claudio Martella from VUA was presenting Lighthouse: Large-scale graph pattern matching on Giraph.
The presentation starts giving a quick overview about Pregel and Apache Giraph to then move to the specifics of Lighthouse and how it was created to use high-level languages to express the graph pattern algorithms (instead of Java). Lighthouse uses Cypher query language (from Neo4j) to express graph patterns, extracting a query graph from the Cypher query and computing a query plan based on Giraph algebra and executed as Giraph computation on Hadoop cluster.
Watch Claudio Martella presenting Lighthouse's Giraph execution algebra in detail:
Stay tuned for the second day of presentations posts!
