Question

Hello everyone I do have a question on pipeline registry how can I specify the order of the pipeline to execute

Eluard Camota · Answer

Or better question is how do I connect the disconnected pipelines on pipeline registry py

Nok Lam Chan · Answer

Can you explain what you are trying to do It may help to understand the context better since these 2 questions are quite different

Eluard Camota · Answer

I have 3 different pipelines created using `kedro pipeline create` Those pipelines are disconnected since it doesn t contain the output from the previous nodes So what I m trying to do is to register those 3 different pipelines on the `pipeline registry py` and connect each pipeline after another pipeline

Nok Lam Chan · Answer

I see so you just want to run all pipelines together right

Nok Lam Chan · Answer

You don t need to do anything special pipelines can be disconnected In your `pipeline registry py` you can add `pipelines all = pipelines a + pipelines b + pipelines c ` or whatever name you preferred

Nok Lam Chan · Answer

You can then run `kedro viz` to confirm it they should be just 3 parallel pipelines

Eluard Camota · Answer

for example pipeline b should only run once pipeline a is done running

Eluard Camota · Answer

and pipeline c will run only after pipeline b is finished

Nok Lam Chan · Answer

what does these pipeline do and why it has to be run after another pipeline without any explicit dependencies

Nok Lam Chan · Answer

the execution order is determined by Node dependencies that is a node has some input and output Kedro then try to resolve this graph If you need to guarantee this order then your last node of pipeline a should produce something that the first node of pipeline b would take
