We’re pleased to announce that three of our technical experts will present a talk and demonstration at the November Data Works MD Meetup. Senior software engineers Bill Farmer, Ryan Hendrickson, and Elli Schwarz spend the workweek collaborating on complex technical challenges — they will bring their dataflow expertise to the Data Works group with their presentation, Connect Data and Devices with Apache NiFi.

 

The Meetup is scheduled for Thursday, November 7, from 6:30 pm until 8 pm in CACI’s auditorium at 2720 Technology Drive in Annapolis Junction.

What is NiFi?

Apache NiFi is an intuitive, scalable, and customizable system used to process and distribute data. It comes with an easy-to-use and appealing management UI, a large market of standard processors, and a vibrant Open Source Community supporting it.

 

About the presentation

An accessible how-to

Clarity’s team aims to provide an accessible how-to that will walk participants through NiFi basics, showing practical examples that are easy to follow. The Meetup group will learn how to use NiFi to move data across servers and networks, as well as how to manipulate, enrich, and stream data using custom processors.

 

Data manipulation and open-source tools

Specific how-tos will include performing data manipulation using:

 

  •       a custom Java processor
  •       the ExecuteScript processor, with JavaScript and Python
  •       the JoltTransformData processor

 

The team will demonstrate open-source tools, such as Jolt, jQ, and JsonPath. The presentation will explain how to prototype a REST service with standard processors. Expect light bulbs to flash from (exciting) things happening in NiFi!
