This talk was recorded at Scala Days New York, 2016. Follow along on Twitter @scaladays and on the website for more information http://scaladays.org/. Abstract: In this talk we will go over the architecture and implementation of a large-scale graph analysis engine using Scala, Akka and Hbase. Starting from the needs that led to this type of processing, we’ll go through the different implementation considerations, jump into an implementation that includes a query parser and an akka cluster to do the processing, and then see how we can produce a stream output of the results. This talk could benefit anyone that is interested in Scala, Akka, Big Data, stream processing and of course graphs.
