I have no idea what I'm doing wrong. I synched this repo <https://github.com/databricks-academy/apache-spark-programming-with-databricks> as instructed. You can see that Notebook 4.1 is query optimization in the 'published' branch.

https://github.com/databricks-academy/apache-spark-programming-with-databricks/blob/published/ASP%20...

But... In the lesson that's Streaming Query. Streaming Query is notebook 5.1 in the repo.

I'm pretty confident that I'm on the correct branch, as I'm on the default branch and it has the very reassuring name 'published.' Am I in the wrong set of videos? Do they just not match up?

Help!
