Summary: Speed up MiNiFi Build with Conan package manager (C++)
Key: MINIFICPP-2346
URL: https://issues.apache.org/jira/browse/MINIFICPP-2346
Project: Apache NiFi MiNiFi C++
Issue Type: Improvement
Affects Versions: 0.15.0
Environment: Ubuntu 22.04
Reporter: James Medel
Assignee: James Medel
*Description of Issue:* Building MiNiFi C++ with just CMake is really slow.
During the the build process, it clones all the external dependencies and then
builds those external dependencies while its building MiNiFi C++. It would be
faster to build MiNiFi C++ with the external dependencies already preinstalled.
*Potential Solution:* Integrate *conan version 2* into MiNiFi C++ project to
enable support for using *conan install* to install all or most of MiNiFi's
external dependencies, using *conan install --build=missing* to build them as
prebuilt binary conan packages, upload them to conancenter with {*}conan
upload{*}, and then run cmake generate to generate the appropriate build files
for the OS, then run make to build MiNiFi C++. At this point because we already
most of MiNiFi C++'s external dependencies with conan, our CMake build will
just focus on building the MiNiFi C++ code.
*Steps to Perform MiNiFi C++ Build Enhancement:*
# Install conan version 2 into MiNiFi C++ dev environment (my preference is
using docker container)
# Create a conanfile.py file at root of MiNiFi C++ project where we run "conan
install" or "conan install --build=missing" to install MiNiFi C++ external lib
dependencies first. Then we run CMake to build MiNiFi C++.
# Find all MiNiFi C++ find_package(...) CMake function calls and check if
there is already supported conan packages on the conancenter, so we can install
those packages.
# Find all FetchContent_Declare(...) CMake function calls and check if there
is already supported conan packages on the conancenter, so we can install those
packages.
# At this point we will have used conan version 2 C++ package manager to
install almost all MiNiFi C++'s external dependencies.
## With Conan, we will have installed these MiNiFi external lib dependencies
as prebuilt binary conan packages.
## Or we will have instructed conan to first build each C++ external lib
dependency, upload each lib to conancenter.
# Thus, conan manages installing MiNiFi C++'s external lib dependencies, so we
can then run CMake to build MiNiFi faster.
