Summary
In this Appendix, you learned the basics of NiFi clustering, as well as how to build a cluster with the embedded Zookeeper and how to build distributed data pipelines. NiFi handles most of the distribution of data; you only need to keep in mind the gotchas – such as race conditions and the fact that processors need to be configured to run on any node. Using a NiFi cluster allows you to manage NiFi on several machines from a single instance. It also allows you to process large amounts of data and have some redundancy in case an instance crashes.
