Course Outline
NiFi Fundamentals and Data Flow
- Data in motion versus data at rest: understanding concepts and challenges
- NiFi architecture: cores, flow controller, provenance, and bulletin
- Core components: processors, connections, controllers, and provenance
Big Data Context and Integration
- NiFi's role within Big Data ecosystems (Hadoop, Kafka, cloud storage)
- Overview of HDFS, MapReduce, and contemporary alternatives
- Use cases: stream ingestion, log shipping, and event pipelines
Installation, Configuration & Cluster Setup
- Installing NiFi in both single-node and cluster modes
- Cluster configuration: defining node roles, utilizing Zookeeper, and load balancing
- Orchestrating NiFi deployments using Ansible, Docker, or Helm
Designing and Managing Dataflows
- Routing, filtering, splitting, and merging flows
- Configuring processors (e.g., InvokeHTTP, QueryRecord, PutDatabaseRecord)
- Managing schema, enrichment, and transformation operations
- Managing error handling, retry relationships, and backpressure
Integration Scenarios
- Connecting to databases, messaging systems, and REST APIs
- Streaming to analytics systems such as Kafka, Elasticsearch, or cloud storage
- Integrating with Splunk, Prometheus, or logging pipelines
Monitoring, Recovery & Provenance
- Utilizing the NiFi UI, metrics, and the provenance visualizer
- Designing autonomous recovery and graceful failure handling
- Implementing backup, flow versioning, and change management
Performance Tuning & Optimization
- Tuning JVM, heap, thread pools, and clustering parameters
- Optimizing flow design to minimize bottlenecks
- Managing resource isolation, flow prioritization, and throughput control
Best Practices & Governance
- Flow documentation, naming standards, and modular design
- Security protocols: TLS, authentication, access control, and data encryption
- Change control, versioning, role-based access, and audit trails
Troubleshooting & Incident Response
- Addressing common issues such as deadlocks, memory leaks, and processor errors
- Log analysis, error diagnostics, and root cause investigation
- 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

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.
