The NodeGuardian actor is the root supervisor of this simple Akka application's ActorSystem node that you might deploy across a cluster.
A simple Akka actor which generates a pre-set number of random tuples based on initial input
data
, and sends each random tuple to the Streamer.
Simply showing what the streaming actor does for the sake of the demo.
This demo can run against a single node, local or remote.
This demo creates a table in Cassandra, populates it with sample data, then queries it using SparkSQL and finally displays the query results to the standard output.
