Lightning Talk: C++ in the Cloud: One NIF at a Time with Elixir

on YouTube ↗05m

" summary

C++ code compiles into a shared library (named lib_exj_boost in the example) and is called from Elixir via Native Implemented Functions to reuse an optimized C++ library (example: an exj_boost_build_info NIF that returns build metadata). This brings raw CPU performance into Elixir services, works in practice, and requires keeping NIF execution under 1 ms and careful crash handling because a NIF crash can take down the BEAM.
