F# Advent 2021 Dec 08 - Fast data pipelines with F#6

Thanks to Sergey Tihon for running F# Weekly and F# Advent.

Thanks to manofstick for trying out the code and coming with invaluable feedback. Cistern.ValueLinq is very impressive.

TLDR; F#6 enables data pipelines with up to 15x less overhead than LINQ

There were many interesting improvements in F#6 but one in particular caught my eye, the attribute InlineIfLambda.

Architecture

• Use Onion architecture

  • Dependencies go inwards. That is, the Core domain doesn't know about outside layers

• Use pipeline model to implement workflows/use-cases/stories

  • Business logic makes decisions
  • IO does storage with minimal logic
  • Keep Business logic and IO separate

• Keep IO at edges
