Course Outline
NiFi and Data Flow Fundamentals
- Comparing data in motion versus data at rest: key concepts and associated challenges
- NiFi architecture overview: core components, flow controller, provenance, and bulletin
- Essential elements: processors, connections, controllers, and provenance tracking
Big Data Context and Integration
- The role of NiFi within Big Data ecosystems, including Hadoop, Kafka, and cloud storage
- An overview of HDFS, MapReduce, and modern alternatives
- Practical use cases: stream ingestion, log shipping, and event pipelines
Installation, Configuration, and Cluster Setup
- Installing NiFi in both single-node and cluster modes
- Configuring clusters: defining node roles, Zookeeper integration, and load balancing
- Orchestrating NiFi deployments using tools such as Ansible, Docker, or Helm
Designing and Managing Dataflows
- Techniques for routing, filtering, splitting, and merging flows
- Configuring processors (e.g., InvokeHTTP, QueryRecord, PutDatabaseRecord)
- Managing schemas, enrichment, and transformation operations
- Implementing error handling, retry relationships, and backpressure mechanisms
Integration Scenarios
- Connecting to databases, messaging systems, and REST APIs
- Streaming data to analytics systems such as Kafka, Elasticsearch, or cloud storage
- Integrating with Splunk, Prometheus, or logging pipelines
Monitoring, Recovery, and Provenance
- Utilizing the NiFi UI, metrics, and the provenance visualizer
- Designing strategies for autonomous recovery and graceful failure handling
- Managing backups, flow versioning, and change control
Performance Tuning and Optimization
- Tuning JVM settings, heap memory, thread pools, and clustering parameters
- Optimizing flow design to minimize bottlenecks
- Applying resource isolation, flow prioritization, and throughput control
Best Practices and Governance
- Documenting flows, establishing naming standards, and adopting modular design
- Security measures: TLS, authentication, access control, and data encryption
- Implementing change control, versioning, role-based access, and audit trails
Troubleshooting and Incident Response
- Addressing common issues such as deadlocks, memory leaks, and processor errors
- Performing log analysis, error diagnostics, and root cause investigations
- Developing recovery strategies and flow rollback procedures

Hands on exercises. Class should have been 5 days, but the 3 days helped to clear up a lot of questions that I had from working with NiFi already

Course - Apache NiFi for Administrators
I thought the trainer's pace was good. He left no student behind with his approach. He was very supportive with us NEWBIES that may not have had a System Administrator or Infrastructure role during our career or resurrected those skills from a prior period of our career.

I like the hands on section. It helped me to better retain information by completing the provided exercises. Also, the trainer's ability to engage with the entire class made me feel comfortable to ask questions on things I was not sure about.

Use-cases, examples for building NiFi dataflows. We worked on troubleshooting common problems and gotchas.
Nelson - BHG Financial
Course - Apache NiFi for Administrators
I loved the structure. We dove into the basics of Nifi, concepts, use cases, etc. on day 1. On day 2, we got to put Day 1 knowledge into practice by building out flows to meet scenario requirements. Day 3 we got to see Nifi Registry and version control, mulit-tenancy, and go over Q&A.
Adam - BHG Financial
Course - Apache NiFi for Administrators
I like how he was able to elaborate about Nifi and how powerful it is. You can basically use it for any infrastructure and use many different computer languages. Also i was glad we were able to fix the Nifi cert renewal issue we were having with the Truststore.
