Hi all, can I configure the use of ParallelRunner only on the command line or also in parameters.yml?

Someone will reply to you shortly. In the meantime, this might help:

you can do this with a YAML file via

kedro run --config your_params.yml

but that's independent from parameters. https://docs.kedro.org/en/stable/nodes_and_pipelines/run_a_pipeline.html#configure-kedro-run-arguments

Great. Thanks!
