Thanks for your answer!

Different cluster per notebook does what I need, for now.

Solution with REST API 2.0 to resize cluster seems more flexible way to go. I guess it should be possible to create clusters on demand, from JSON configs, via curl command?

Ideally, I'd like to achieve ADF pipeline deployment from some code (JSON or python), where I can configure resources to be used at each step (on demand), and with packages versions to be installed at each cluster.

Thank you!
