Por que usar grafos
Modelagem intuitiva
Queries expressivas
Casos de uso Recomendações personalizadas Influência social
Casos de uso Melhor rota Detecção de fraude
Quero usar grafos! #comofas?
Apache TinkerPop • Vendor-agnostic graph compute framework • Gremlin -
graph traversal language • Capacidades OLTP e OLAP
Core API Graph graph = TinkerGraph.open(); Vertex nosql =
graph.addVertex("trilha"); nosql.property("nome", "NoSQL"); Vertex tdc2016 = graph.addVertex("evento"); tdc2016.property("nome", "TDC 2016"); Edge e = nosql.addEdge("compoe", tdc2016); e.property("data", "08/07/2016");
Core API Graph graph = Neo4jGraph.open("..."); Vertex nosql =
graph.addVertex("trilha"); nosql.property("nome", "NoSQL"); Vertex tdc2016 = graph.addVertex("evento"); tdc2016.property("nome", "TDC 2016"); Edge e = nosql.addEdge("compoe", tdc2016); e.property("data", "08/07/2016");
TinkerPop-enabled Vendors TitanGraph.open(…) Neo4jGraph.open(…) OrientGraph.open(…) StardogGraph.open(…) DSEGraph.open(…) BlazeGraph.open(…)
Gremlin lang What are the names of Gremlin's friends' friends?
g.V().has("name","gremlin"). out("knows"). out("knows"). values("name")
Gremlin console
OLTP vs OLAP
Spark computer graph = GraphFactory.open(…); g = graph.traversal(). withComputer(SparkGraphComputer.class);
g.V().hasLabel("person").groupCount().by("age")
Giraph computer graph = GraphFactory.open(…); g = graph.traversal(). withComputer(GiraphGraphComputer.class);
g.V().hasLabel("person").groupCount().by("age")
Gremlin server REST WebSockets
