20:30 Fishing Graphs in a Hadoop Data Lake by Max Neunhöffer (@neunhoef)

Hadoop clusters can store nearly everything in a cheap and blazingly fast way to your data lake. Answering questions and gaining insights out of this ever growing stream becomes the decisive part for many businesses. Increasingly data has a natural structure as a graph, with vertices linked by edges, and many questions arising about the data involve graph traversals or other complex queries, for which one does not have an a priori given bound on the length of paths.

Spark with GraphX is great for answering relatively simple graph questions which are worth starting a Spark job for, because they essentially involve the whole graph. But does it make sense to start one for every ad-hoc query or is it suitable for complex real-time queries?
