So I found another low-end affordable platform from China for running MiniFi goodness. For this 512MB RAM machine, I decided to use MiniFi CPP.

git clone https://github.com/apache/nifi-minifi-cpp.git
apt-get install cmake   gcc g++   bison   flex   libcurl-dev   librocksdb-dev librocksdb4.1   uuid-dev uuid   libboost-all-dev libssl-dev   libbz2-dev liblzma-dev   doxygen -y
apt-get install -y libleveldb-dev
apt-get install -y libxml2
apt-get install libpython3-dev -y
apt-get install liblua5.1-0-dev -y
apt-get install libusb-1.0.0-0-dev libpng12-dev -y
apt-get install docker.io python-virtualenv -y
 apt-get install libpython3-dev -y
apt-get install libgps-dev -y
apt-get install libpcap-dev -y
apt-get install cmake   gcc g++   bison   flex -y 
./bootstrap.sh
interactive UI
cd nifi-minifi-cpp-0.3.0-source/
mkdir build
cd build
cmake ..
make
make package
apt-get install libssl-dev 
-- The following features have been enabled:
 * EXPRESSION LANGUAGE EXTENSIONS , This enables NiFi expression language
 * HTTP CURL , This enables RESTProtocol, InvokeHTTP, and the HTTPClient for Site to Site
 * ROCKSDB REPOS , This Enables persistent provenance, flowfile, and content repositories using RocksDB
 * ARCHIVE EXTENSIONS , This Enables libarchive functionality including MergeContent, CompressContent, (Un)FocusArchiveEntry and ManipulateArchive.
 * SCRIPTING EXTENSIONS , This enables scripting
-- The following OPTIONAL packages have been found:
 * LibRt
 * Git
 * BZip2
 * LibLZMA
 * EXPAT
 * Boost
 * Doxygen
-- The following REQUIRED packages have been found:
 * BISON
 * FLEX
 * CURL
 * Threads
 * PythonLibs
 * ZLIB
 * UUID
 * OpenSSL
-- The following features have been disabled:
 * CIVETWEB , This enables ListenHTTP
-- The following OPTIONAL packages have not been found:
 * WinSock
 * RocksDB
 * LibArchive
 * Nettle
 * LibXml2

This will take some library installs for development and various libraries needed for networking, security and devices.

From the interactive UI, I selected to add most of the goodies except a USB camera since I don't have one on this tiny machine.

The CPP is different (and much smaller) than the Java one. For first, you have a specific set of processors, some of which are pretty cool like ones for USB Camera image ingestion, TensorFlow processing and other device goodness. You can browse the list in the PROCESSORs link below.

Since I built mine from the git clone of the master, I am running the 0.4.0 branch.

I could not install RocksDB on OrangePi

There's some cool stuff for reporting status.
