is it possible to create and run nodes parallel in a loop?

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

if you do

kedro run --runner ParalellRunner

all nodes that can be run concurrently will be

So it is not possible to create multiple nodes from a single node in a loop? e.g. an rss scraper node which for each record submits a single not to preprocess it?

so you can do that within a node, but you'd have to manage the parallism with something like

joblib

, if you do that you can't use Kedro's node level parallel splitting

Okay! Do you know where in the docs I can find how to crerate the nodes dynamically?

We don't officially recommend creating nodes or pipelines dynamically, so we don't have any docs about that. Our collaborators at GetInData have written a blog post https://getindata.com/blog/kedro-dynamic-pipelines/, but it's more about dynamically creating pipelines. It might help though.
