diff commits to your kedro pipeline

pip install kedro-diff==0.1.0



kedro-diff aims to be a familiar interface into comparing two points in history. Git diffs are fantastic tools but often are too granular to see what has changed inside the pipeline. kedro-diff aims to be a familiar tool at a higher level so we can see changes to nodes (names, inputs, outputs, tags).


pip install kedro-diff


kedro diff --stat develop..master
M  __default__      | 6 ++++-
M  data_science     | 3 +++
M  data_engineering | 3 ++-
?? new_pipeline

4 pipelines changed, 5 insertions(+), 4 deletions(-)

  • commit parser
  • get pipeline.to_json() for __default__ for two different commits
  • get pipeline.to_json() for all pipelines for two different commits
  • --stat compares the number of nodes added or dropped in __default__
  • --stat compares the number of nodes added or dropped in all pipelines
  • --stat compares attribute changes (inputs, outputs, tags) in all pipelines
  • compare input names
  • compare output names
  • speed up getting repeat pipelines from the same commit (no need to reaload a new session)
  • speed up getting repeat commits by checking commit hash (reuse existing json)
  • minimize untested code


super-size pipeline.to_json()

  • compare all attributes on a node ( not just inputs, outputs, tags)
  • allow users to specify custom to_json method
  • function names
  • function hashes
  • catalog _filepath
  • catalog _sql


This project strives for 100% test coverage where it makes sense. Other kedro plugins I have created have suffered development speed by the complexity of fully testing on a full kedro project. There are so many pieces to get into place that it becomes difficult to test accross multiple versions of kedro or keep the tests working as kedro changes. Minimal functionality will be placed into modules that require a kedro full kedro project in place to work.
