Course Outline
NiFi Fundamentals and Data Flow Concepts
- Distinguishing between data in motion and data at rest: key concepts and associated challenges
- NiFi architecture: core components, flow controller, provenance, and bulletin board
- Essential elements: processors, connections, controllers, and provenance tracking
Big Data Context and Integration
- The position of NiFi within Big Data ecosystems (including Hadoop, Kafka, and cloud storage)
- An overview of HDFS, MapReduce, and contemporary alternatives
- Application cases: stream ingestion, log transmission, and event pipelines
Installation, Configuration & Cluster Setup
- Setting up NiFi in both single-node and cluster modes
- Configuring clusters: node roles, Zookeeper integration, and load balancing strategies
- Managing NiFi deployments using tools like Ansible, Docker, or Helm
Designing and Managing Dataflows
- Techniques for routing, filtering, splitting, and merging data flows
- Configuring processors (such as InvokeHTTP, QueryRecord, PutDatabaseRecord, etc.)
- Managing schemas, enrichment processes, and transformation operations
- Implementing error handling, retry mechanisms, and backpressure management
Integration Scenarios
- Connecting to databases, messaging systems, and REST APIs
- Streaming data to analytics platforms like Kafka, Elasticsearch, or cloud storage services
- Integrating with monitoring and logging tools such as Splunk, Prometheus, or custom logging pipelines
Monitoring, Recovery & 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 & Optimization
- Adjusting JVM settings, heap size, thread pools, and clustering parameters
- Refining flow designs to minimize bottlenecks
- Implementing resource isolation, flow prioritization, and throughput regulation
Best Practices & Governance
- Establishing flow documentation, naming conventions, and modular design standards
- Security measures: TLS, authentication, access control, and data encryption
- Enforcing change control, versioning, role-based access, and maintaining audit trails
Troubleshooting & Incident Response
- Addressing common issues: deadlocks, memory leaks, and processor errors
- Conducting log analysis, error diagnostics, and root cause investigations
- Applying recovery strategies and flow rollback procedures
Hands-on Lab: Implementing a Realistic Data Pipeline
- Constructing an end-to-end flow covering ingestion, transformation, and delivery
- Implementing error handling, backpressure, and scaling capabilities
- Conducting performance testing and pipeline tuning

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

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.
