i am really interest in big data and started to learn about SMACK. I already set up a small pipeline: Kafka Producers > Kafka > Spark Streaming> Cassandra. Now I want to plot my incoming data(live). What would be the best time to plot? After the data arrived (but i want to manipulate) in Kafka? In or after spark? Or after i saved everything in cassandra? What would be the appropriat technology?
Thanks for your input!
