I have a pipeline with two different data processing pipelines, I would like to control which branch is run using parameters.yml. Both pipelines are part of the default pipeline. Is there a way I can use the

before_pipeline_run

hook to prevent the pipeline from running? The logic is working in the hook to know which pipeline I don't want to run but I can't figure out a way to prevent the pipeline from running.

Not directly answering your question. Alternative is having them as two separate pipeline registry and do

kedro run --pipeline a

and

kedro run --pipeline b

instead of injecting dynamic behavior

Thanks for the suggestion! I'm sure that's the best way to do it. I had also tried skipping individual nodes in

before_node_run

, which I was able to get to not run nodes but was still loading the data for unused nodes.

What about tags? Do you really have to use

parameters.yml

?
