What you'll be able to do

• Trace how a notebook actually runs in Databricks — workspace, cluster, notebook, jobs, repos, libraries and Unity Catalog
• Tell the notebook you edit from the compute that runs it, and explain what happens when a cluster terminates
• Explain what a lakehouse is, and how storage, tables and catalogs sit underneath the notebook you are looking at
• Choose the right cluster — small vs. large, single node vs. autoscaling, job vs. all-purpose — and see how that choice changes cost
• Explain why an idle all-purpose cluster is the most common source of unexpected Databricks spend
