Wrapping Up
Explore how GenStage enables robust data processing pipelines with back-pressure in Elixir. Understand ConsumerSupervisor for scaling workloads, diverse configurations for versatility, and the challenges and solutions in setting up concurrent pipelines for resilient and efficient systems.
This chapter wasn’t the easiest, so congratulations on completing it! Although slightly intimidating at first, GenStage is a brilliant tool that gives Elixir an advantage over other programming languages. Of course, as Elixir’s creator José Valim has pointed out many times, none of it would be possible without Erlang’s rock-solid OTP serving as a foundation.
Back-pressure
This chapter looked at back-pressure and its problems when building and scaling data processing pipelines.
