Hi @oakhill , as stated above, in order for DLT notebooks to work well you need to create a pipeline (which it sounds like you did!).

You are correct - running a notebook cell will trigger a "Validate" action on the entire pipeline code. Alternatively, you could go to the DLT pipeline UI and trigger a "selective refresh" of one or several of your tables if you're not interested in running the entire pipeline code. https://docs.databricks.com/en/delta-live-tables/updates.html#start-a-pipeline-update-for-selected-t...

In general, you can read more about the DLT notebook development experience updates in this blog post https://www.databricks.com/blog/dlt-pipeline-development-made-simple-notebooks

Please don't hesitate to reach out if you have any more questions or feedback.

Regards,

Zoé
