Apache NiFi Engineering
Production NiFi clusters orchestrating enterprise data flows across hundreds of sources. We architect flow-based integration pipelines, CDC routing, data provenance infrastructure, and MiNiFi edge collection with backpressure tuning and guaranteed delivery.

Flow-Based Data Integration Infrastructure
We design and operate Apache NiFi clusters that handle enterprise-grade data routing — from CDC capture and protocol mediation to compliance-driven data provenance across regulated industries.
What We Build
| Capability | What We Deliver |
|---|---|
| CDC pipelines | change data capture from PostgreSQL, MySQL, and Oracle with NiFi processors, routed to Kafka, S3, or data warehouses with exactly-once guarantees |
| Enterprise data routing | content-based routing across hundreds of data sources with prioritized queues, backpressure thresholds, and automatic failover |
| Edge collection with MiNiFi | lightweight agents on IoT gateways and edge nodes pushing telemetry to central NiFi clusters via Site-to-Site protocol |
| Data provenance and lineage | full chain-of-custody tracking for every FlowFile, meeting HIPAA, SOX, and GDPR audit requirements |
Engineering Standards
- NiFi Registry for version-controlled flow definitions across dev, staging, and production environments
- Backpressure tuning: queue size and data size thresholds calibrated per connection to prevent memory exhaustion
- Custom processors in Java for domain-specific transformation logic not covered by the 300+ built-in processors
- Cluster coordination via ZooKeeper with automatic primary node election and zero-downtime scaling
- Monitoring: NiFi reporting tasks feeding Prometheus + Grafana for throughput, queue depth, and bulletin alerts
- Sensitive parameter contexts with encrypted storage for credentials and API keys
Depth of Practice
We maintain published technical content on data integration architecture, ETL pipeline design, and streaming ingestion patterns on the ActiveWizards blog. Our engineers operate NiFi deployments processing millions of FlowFiles daily across financial services, healthcare, and logistics domains.
