Apache NiFi - MiNiFi - C++ Linux/Mac Build Status Windows Build Status

MiNiFi is a child project effort of Apache NiFi. This repository is for a native implementation in C++.

Table of Contents


Apache NiFi - MiNiFi C++ is a complementary data collection approach that supplements the core tenets of NiFi in dataflow management, focusing on the collection of data at the source of its creation. The C++ implementation is an additional implementation to the one in Java with the aim of an even smaller resource footprint.

Specific goals for MiNiFi comprise:

  • small and lightweight footprint
  • central management of agents
  • generation of data provenance
  • integration with NiFi for follow-on dataflow management and full chain of custody of information

Perspectives of the role of MiNiFi should be from the perspective of the agent acting immediately at, or directly adjacent to, source sensors, systems, or servers.

Expression Language

A subset of the Apache NiFi Expression Language is supported.


MiNiFi - C++ supports the following C++ processors:

The following table lists the base set of processors.

Extension Set Processors
Base AppendHostInfo

The next table outlines CMAKE flags that correspond with MiNiFi extensions. Extensions that are enabled by default ( such as CURL ), can be disabled with the respective CMAKE flag on the command line.

Through JNI extensions you can run NiFi processors using NARs. The JNI extension set allows you to run these Java processors. MiNiFi C++ will favor C++ implementations over Java implements. In the case where a processor is implemented in either language, the one in C++ will be selected; however, will remain transparent to the consumer.

Extension Set Processors CMAKE Flag
Archive Extensions ApplyTemplate
AWS AWSCredentialsService -DENABLE_AWS=ON
Scripting ExecuteScript
Custom Python Processors
SQLLite ExecuteSQL
Tensorflow TFApplyGraph

Please see our Python guide on how to write Python processors and use them within MiNiFi C++.


  • 0.7.0 represents a GA-release. We follow semver so you can expect API and ABI compatibility within minor releases. See semver's website for more information
  • Build and usage currently only supports Linux and OS X environments. MiNiFi C++ can be built and run through the Windows Subsystem for Linux but we provide no support for this platform.
  • Native Windows builds are possible with limited support. OPENSSL_ROOT_DIR must be specified to support OpenSSL support within your build.
  • Provenance events generation is supported and are persisted using RocksDB. Volatile repositories can be used on systems without persistent storage.

System Requirements

To build


  • CMake
    • 3.1 or greater
  • gcc
    • 4.8.4 or greater
  • g++
    • 4.8.4 or greater
  • bison
    • 3.0.x (3.2 has been shown to fail builds)
  • flex
    • 2.5 or greater
External Projects

The following utilities are needed to build external projects, when bundled versions of LibreSSL, cURL, or zlib are used:

  • patch
  • autoconf
  • automake
  • libtool

NOTE if Lua support is enabled, then a C++ compiler with support for c++-14 must be used. If using GCC, version 6.x or greater is recommended.

NOTE if bustache (ApplyTemplate) support is enabled, a recent version of a compiler supporting c++-11 must be used. GCC versions >= 6.3.1 are known to work.

NOTE if Kafka support is enabled, a recent version of a compiler supporting C++-11 regexes must be used. GCC versions >= 4.9.x are recommended.

NOTE if Expression Language support is enabled, FlexLexer must be in the include path and the version must be compatible with the version of flex used when generating lexer sources. Lexer source generation is automatically performed during CMake builds. To re-generate the sources, remove:

  • extensions/expression-language/Parser.cpp
  • extensions/expression-language/Parser.hpp
  • extensions/expression-language/Scanner.cpp
  • extensions/expression-language/location.hh
  • extensions/expression-language/position.hh
  • extensions/expression-language/stack.hh

and rebuild.

Libraries / Development Headers

  • libboost and boost-devel
    • 1.48.0 or greater
  • libcurl-openssl (If not available or desired, NSS will be used)
  • librocksdb4.1 and librocksdb-dev
  • libuuid and uuid-dev
  • openssl
  • Python 3 and development headers -- Required, unless Python support is disabled
  • Lua and development headers -- Optional, unless Lua support is enabled
  • libgps-dev -- Required if building libGPS support


CentOS 6

Additional environmental preparations are required for CentOS 6 support. Before building, install and enable the devtoolset-6 SCL:

$ sudo yum install centos-release-scl
$ sudo yum install devtoolset-6
$ scl enable devtoolset-6 bash

Additionally, for expression language support, it is recommended to install GNU Bison 3.0.4:

$ wget
$ tar xvf bison-3.0.4.tar.xz
$ cd bison-3.0.4
$ ./configure
$ make
$ sudo make install

Finally, it is required to add the -lrt compiler flag by using the -DCMAKE_CXX_FLAGS=-lrt flag when invoking cmake.

On all distributions please use -DUSE_SHARED_LIBS=OFF to statically link zlib, libcurl, and OpenSSL.


SLES 11 requires manual installation of the SDK using the following link: Once these are installed you will need to download and build CMAKE3, OpenSSL1.0, and Python3. Once these are installed follow the cmake procedures. The bootstrap script will not work.

SLES 12 requires you to enable the SDK module in YAST. It is advised that you use the bootstrap script to help guide installation. Please see the Bootstrapping section below.


Build and Installation has been tested with Windows 10 using Visual Studio. You can build and create an MSI via the CPACK command. This requires the installation of the WiX toolset ( To do this, open up a prompt into your build directory and type 'cpack' . The CPACK command will automatically generate and provide you a path to the distributable msi file.

To run


  • libuuid
  • libcurl-openssl (If not available or desired, NSS will be used)
  • libssl and libcrypto from openssl
  • libarchive
  • librdkafka
  • Python 3 -- Required, unless Python support is disabled
  • Lua -- Optional, unless Lua support is enabled
  • libusb -- Optional, unless USB Camera support is enabled
  • libpng -- Optional, unless USB Camera support is enabled
  • libpcap -- Optional, unless ENABLE_PCAP specified

The needed dependencies can be installed with the following commands for:

Yum based Linux Distributions

NOTE if a newer compiler is required, such as when Lua support is enabled, it is recommended to use a newer compiler using a devtools-* package from the Software Collections (SCL).

Getting Started


  • MiNiFi C++ offers a bootstrap script in the root of our github repo that will boot strap the cmake and build process for you without the need to install dependencies yourself. To use this process, please run the command from the root of the MiNiFi C++ source tree.

  • Per the table, below, you will be presented with a menu guided bootstrap process. You may enable and disable extensions ( further defined below ). Once you are finished selecting the features you wish to build, enter N to continue with the process. CMAKE dependencies will be resolved for your distro. You may enter command line options -n to force yes to all prompts ( including the package installation prompts ) and -b to automatically run make once the cmake process is complete. Alternatively, you may include the package argument to boostrap, -p, which will run make package.

  • If you provide -b or -p to, you do not need to follow the Building section, below. If you do not provide these arguments you may skip the cmake .. section from Building.

    # ~/Development/code/apache/nifi-minifi-cpp on git:master
    $ ./
    # CMAKE Build dir exists, should we overwrite your build directory before we begin?
      If you have already bootstrapped, bootstrapping again isn't necessary to run make [ Y/N ] Y

  • Boostrap now saves state between runs. State will automatically be saved. Provide -c or --clear to clear this state. The -i option provides a guided menu install with the ability to change advanced features.


  • From your source checkout, create a directory to perform the build (e.g. build) and cd into that directory.

    # ~/Development/code/apache/nifi-minifi-cpp on git:master
    $ mkdir build
    # ~/Development/code/apache/nifi-minifi-cpp on git:master
    $ cd build
  • Perform a cmake .. to generate the project files

    # ~/Development/code/apache/nifi-minifi-cpp on git:master
    $ cmake ..

Building For Other Distros

If you have docker installed on your machine you can build for CentOS 7, Fedora 29, Ubuntu 16, Ubuntu 18, and Debian 9 via our make docker commands. The following table provides the command to build your distro and the output file in your build directory. Since the versions are limited ( except for Ubuntu ) we output the archive based on the distro's name.

Distro command Output File
CentOS 7 make centos nifi-minifi-cpp-centos-$VERSION-bin.tar.gz
Debian 9 make debian nifi-minifi-cpp-debian-$VERSION-bin.tar.gz
Fedora 29 make fedora nifi-minifi-cpp-fedora-$VERSION-bin.tar.gz
Ubuntu 16 make u16 nifi-minifi-cpp-xenial-$VERSION-bin.tar.gz
Ubuntu 18 make u18 nifi-minifi-cpp-bionic-$VERSION-bin.tar.gz


Remove the build directory created above.

# ~/Development/code/apache/nifi-minifi-cpp on git:master
$ rm -rf ./build


Snapcraft builds are supported. As per Snapcraft's official recommendations, we recommend using Ubuntu 16.04 as a build system when building the Snap. To build the snap, run

$ snapcraft

from the project directory. Further instructions are available in the Snapcraft documentation.


The 'conf' directory in the root contains a template config.yml document,, and Please see our Configuration document for details on how to configure agents.


After completing a build, the application can be run by issuing the following from :

$ ./bin/ start

By default, this will make use of a config.yml located in the conf directory. This configuration file location can be altered by adjusting the property nifi.flow.configuration.file in located in the conf directory.


MiNiFi can then be stopped by issuing:

$ ./bin/ stop

Installing as a service

MiNiFi can also be installed as a system service using with an optional "service name" (default: minifi)

$ ./bin/ install [service name]

*** Currently windows does not support installing a windows service. ***


MiNiFi C++ comes with a deployment script. This will build and package minifi. Additionally, a file named build_output will be created within the build directory that contains a manifest of build artifacts.

$ <build identifier> 

The build identifier will be carried with the deployed binary for the configuration you specify. By default all extensions will be built.

On Windows it is suggested that MSI be used for installation.


Please see on how to build and run conditionally built dependencies and extensions.


See our operations documentation for additional inforomation on how to manage instances
