Managing data transformation (e.g. dbt) projects at scale can be challenging: DAG violations, that one model that grew to 2K lines, duplicated logic.Inspired by the book 'Building Evolutionary Architectures' I built tff to help data transformation projects evolve in a desired direction. It comes with a github bot that you can plugin to your CI pipeline.It aims to let transformation projects evolve in the desired direction by:

  • ensuring layer boundary integrity;
  • detect duplicate CTE logic;
  • catch violations locally and in CICore concepts: rules apply to models; checks apply to architecture and DAG checks.Curious to read what you think. What can be improved? What's missing? Comments URL: https://news.ycombinator.com/item?id=50294526 Points: 2
