NiFi automates cybersecurity, observability, event streams, and generative AI data pipelines and distribution for thousands of companies worldwide across every industry. - Browser User Interface - Seamless experience for design, control, and monitoring - Runtime management and versioned pipelines - Secure by default with HTTPS - Scalable Processing - Configurable prioritization for throughput and latency - Guaranteed delivery with retry and backoff strategies - Horizontal scaling with clustering - Provenance Tracking - Searchable history with configurable attributes - Graph data lineage from source to destination - Metadata and content for each processing decision - Extensible Design - Plugin interface for Processors and Controller Services - Support for Processors in native Python - REST API for orchestration and monitoring - Secure Configuration - Single sign-on with OpenID Connect or SAML 2 - Flexible authorization policies for role-based access - Encrypted communication with TLS and SFTP ## Requirements NiFi supports modern operating systems and requires recent language versions for developing and running the application. ### Platform Requirements - Java 21 ### Optional Dependencies - Python 3.10 or higher ## Projects The source repository includes several component projects. Please review individual project documentation for additional details. - [Apache NiFi](https://nifi.apache.org/documentation/) - [Apache NiFi Registry](https://github.com/apache/nifi/blob/main/nifi-registry/nifi-registry-assembly/README.md) - [Apache NiFi MiNiFi](https://github.com/apache/nifi/blob/main/minifi/minifi-assembly/README.md) ## Getting Started Project guides provide extensive documentation for installing and extending the application. - [Getting Started](https://nifi.apache.org/documentation/nifi-latest/html/getting-started.html) - [User Guide](https://nifi.apache.org/documentation/nifi-latest/html/user-guide.html) - [Administrator Guide](https://nifi.apache.org/documentation/nifi-latest/html/administration-guide.html) - [Developer Guide](https://nifi.apache.org/documentation/nifi-latest/html/developer-guide.html) ## Developing NiFi uses the [Maven Wrapper](https://maven.apache.org/wrapper/) for project development. The Maven Wrapper provides shell scripts that download and cache a selected version of [Apache Maven](https://maven.apache.org/) for running build commands. Developing on Microsoft Windows requires using `mvnw.cmd` instead of `mvnw` to run Maven commands. ### Building Run the following command to build project modules using parallel execution: ```shell ./mvnw install -T1C ``` Run the following command to build project modules using parallel execution with static analysis to confirm compliance with code and licensing requirements: ```shell ./mvnw install -T1C -P contrib-check ``` Run the following command to build the application binaries without building other optional modules: ```shell ./mvnw install -T1C -am -pl :nifi-assembly ``` ### Binaries The `nifi-assembly` module contains the binary distribution. ```shell ls nifi-assembly/target/nifi-*-bin.zip ``` The `nifi-assembly` module includes the binary distribution in a directory for local development and testing. ```shell cd nifi-assembly/target/nifi-*-bin/nifi-*/ ``` ## Running NiFi provides shell scripts for starting and stopping the system. Running on Microsoft Windows requires using `nifi.cmd` instead of `nifi.sh` for system commands. ### Starting Run the following command to start NiFi from the distribution directory: ```shell ./bin/nifi.sh start ``` ### Accessing The default configuration generates a random username and password on startup. NiFi writes the generated credentials to the application log located in `logs/nifi-app.log` under the NiFi installation directory. The following command can be used to find the generated credentials on operating systems with `grep` installed: ```shell grep Generated logs/nifi-app*log ``` NiFi logs the generated credentials as follows: ```shell Generated Username [USERNAME] Generated Password [PASSWORD] ``` The `USERNAME` will be a random UUID composed of 36 characters. The `PASSWORD` will be a random string. The username and password can be replaced with custom credentials using the following command: ```shell ./bin/nifi.sh set-single-user-credentials <username> <password> ``` NiFi defaults to running on the `localhost` address with HTTPS on port `8443` at the following URL: ``` https://localhost:8443/nifi ``` Browsers will display a warning message indicating a potential security risk due to the self-signed certificate generated during initialization. Production deployments should provision a certificate from a trusted certificate authority and update the NiFi keystore and truststore configuration. ## License Except as otherwise noted this software is licensed under the [Apache License, Version 2.0](https://www.apache.org/licenses/LICENSE-2.0.html) Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
