Flowex 0.2.0 with 'cast' and 'error_pipe'

My talk Flowex - Flow-Based Programming with Elixir GenStage on Elixir Club 5 meetup and following discussions lead me to some significant improvements of the project.

A cast function was added to run calculation asynchronously. And an error handling mechanism was added. Since “0.2.0” each pipeline has error_pipe - separate GenStage for handling errors.

Railway Oriented Programming in Elixir with Pattern Matching on Function Level and Pipelining

Coding seems cool without error checks, does not it? When if/else checks effect the next execution behaviors, then the code becomes a mess. Luckily, there is a pattern called ‘Railway Oriented Programming’ for error handling.

Throttle / Debounce your tasks / operations, group them together!


  • group notifications to be sent in one email

    • cancel the previously queued email if another event happens within a short period (type: debounce / throttle)
  • make heavy operations happen less often, i.e. refresh some global statistics

    • allow only 1 operation per certain period (type: throttle)
  • protect some write api

    • additonally you can choose to use the first value in a period (keep: first)
    • or the last value in the period (keep: last)

Designed to work both on a single node and across nodes in a cluster
