In this section, we provide guides and references to use the NiFi connector. Configure and schedule NiFi metadata and profiler workflows from the OpenMetadata UI:

Requirements

​
Python Requirements

We have support for Python versions 3.9-3.11
To run the NiFi ingestion, you will need to install: 
pip3 install "openmetadata-ingestion[nifi]"

​
Metadata Ingestion

All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to NiFi. In order to create and run a Metadata Ingestion workflow, we will follow the steps to create a YAML configuration able to connect to the source, process the Entities if needed, and reach the OpenMetadata server. The workflow is modeled around the following JSON Schema

​
1. Define the YAML Config

This is a sample config for NiFi:

​
2. Run with the CLI

First, we will need to save the YAML file. Afterward, and with all requirements installed, we can run: 
metadata ingest -c <path-to-yaml>
Note that from connector to connector, this recipe will always be the same. By updating the YAML configuration, you will be able to extract metadata from different sources.
