Provide a top level directory for binary packages.
MiNiFi is a child project effort of Apache NiFi. This repository is for a native implementation in C++.
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 are comprised of:
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.
From your source checkout, create a directory to perform the build (e.g. build) and cd into that directory.

The ‘conf’ directory in the root contains a template config.yml document.
This is compatible with the format used with the Java MiNiFi application. Currently, a subset of the configuration is supported. Additional information on the YAML format for the config.yml can be found in the MiNiFi System Administrator Guide.
Additionally, users can utilize the MiNiFi Toolkit Converter to aid in creating a flow configuration from a generated template exported from a NiFi instance. The MiNiFi Toolkit Converter tool can be downloaded from http://nifi.apache.org/minifi/download.html under the
MiNiFi Toolkit Binaries section. Information on its usage is available at https://nifi.apache.org/minifi/minifi-toolkit.html.

After completing a build, the application can be run by issuing the following from :
$ ./bin/minifi.sh 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 minifi.properties located in the conf directory.
MiNiFi can then be stopped by issuing:
$ ./bin/minifi.sh stop
MiNiFi can also be installed as a system service using minifi.sh with an optional “service name” (default: minifi)
$ ./bin/minifi.sh install [service name]
