Description

One of the most critical functions of a data-driven enterprise is the ability to manage ingest and data flow across complex ecosystems. Does your team have the tools and skill sets to succeed at this?

Apache NiFi and this course provide the fundamental concepts and experience necessary to automate the ingress, flow, transformation, and egress of data using NiFi. The course also covers tuning, troubleshooting, and monitoring the dataflow process as well as how to integrate a dataflow within the Cloudera CDP Hybrid ecosystem and external systems.

Audience and prerequisites

This course is designed for developers, data engineers, administrators, and others with an interest in learning NiFi’s innovative no-code, graphical approach to data ingest. Although programming experience is not required, basic experience with Linux is presumed, and previous exposure to big data concepts and applications is helpful.

Objectives

Students who successfully complete this course will be able to:

  • Define, configure, organize, and manage dataflows
  • Transform and trace data as it flows to its destination
  • Track changes to dataflows with NiFi Registry
  • Use the NiFi Expression Language to control dataflows
  • Optimize dataflows for better performance and maintainability
  • Connect dataflows with other systems, such as Apache Kafka, Apache Hive, and HDFS
  • Utilize the Data Flow Service
