Apache NiFi for Real-Time Data Ingestion

Real-Time Ingestion with Apache NiFi

Apache NiFi is a powerful tool for automating the flow of data between systems.

Key Concepts

  • FlowFile: The actual packet of data.
  • Processor: Performs work on FlowFiles (e.g., GetFile, PutKafka).
  • Connection: Links processors and holds queues.

Best Practices

  1. Backpressure: Configure backpressure to prevent your flow from overwhelming downstream systems.
  2. Version Control: Use the NiFi Registry to manage flow versions.
