README
Flow 
Flow allows developers to express computations on collections, similar to the Enum and Stream modules, although computations will be executed in parallel using multiple GenStages.
Here is a quick example on how to count words in a document in parallel with Flow:
File.stream!("path/to/some/file")
|> Flow.from_enumerable()
|> Flow.flat_map(&String.split(&1, " "))
|> Flow.partition()
|> Flow.reduce(fn -> %{} end, fn word, acc ->
Map.update(acc, word, 1, & &1 + 1)
end)
|> Enum.to_list()
See documentation for Flow or José Valim's keynote at ElixirConf 2016 introducing the main concepts behind GenStage and Flow.
Installation
Flow requires Elixir v1.5 and Erlang/OTP 19+. Add :flow to your list of dependencies in mix.exs:
def deps do
[{:flow, "~> 1.0"}]
end
