Summary: not good and dissappointed. Two parts of the lab confused me and drained a lot of my lab time. The first, which drained the most time, was the switch from the Python27 command line tasks to editing the analyzecompression.py doc. You should make it much more explicit that you are switching to the remote desktop C drive not just assume "C:>Python27" will be understood by all. I was confused for a while and got frustrated. I thought I was opening a Python27 folder using the command prompt. Please make this clearer. The second drain on time came from some syntax issue copying the Redshift endpoint in analyzecompression.py. I missed the inverted commas, but at no point in your notes did you mention the inverted commas. Please amend your texts. Regards, Stuart

Execution plan explanation does not match with the actual query/plan. After WLM reboot, unable to run queries through Worbench.

The Workbench folder doesn't have the application, so can't proceed with the class.
