@mattyb149 @pvillard31 FWIW, I read on the Druid site that you can use
Kafka to load data into Druid instead of Tranquility. I don't know anything
about Tranquility, but working up a flow that uses Kafka to ingest data into
Druid would be a very useful story to deliver to users of NiFi and Druid.---
