Getting Started With Custom Processor for Apache NiFi

Writing Custom Processors for Apache NiFi is easy.   I recommend you start with Apache NiFi 1.20.

You can download from Cloudera or the Apache NiFi site.

You will also need JDK 17 and Maven.   And IDE like Eclipse or IntelliJ IDEA is helpful as well.  I recommend a Linux or OSX machine to develop from.

Just build a new processor shell using:  https://cwiki.apache.org/confluence/display/NIFI/Maven+Projects+for+Extensions
