Mar 04, 2018 · In this post I’ll share a Nifi workflow that takes in CSV files, converts them to JSON, and stores them in different Elasticsearch indexes based on the file schema. I created a JRuby ExecuteScript processor to use the header row of the CSV file as the JSON schema, and the filename to determine which index/type to use for each Elasticsearch document. Intro to Apache Kafka - So the first topic I want to tackle is Kafka Cluster Setup. I want to give you an idea of a high level architecture of what a cluster looks like in production.

For example, in a 25 member cluster with a multicast threshold of 25%, a cluster member only uses multicast if the packet is destined for 6 or more members (24 * .25 = 6). Setting this value to 1 allows the cluster to use multicast for basically all multi-point traffic.
