I LOVE videos like this, and so will you. Short, but powerful with no slides and all demo. Saveen Reddy, Principal PM Manager in the big data team at Microsoft comes in to show how easy it is to debug C# user code in a U-SQL query using local vertex debugging. Saveen spends the first few minutes explaining the challenges for debugging U-SQL when things go wrong in Azure Data Lake Analytics and a clusterless environment. How do you debug? At the [04:00] mark Saveen answers that question by diving right into the demo to show how easy it is by using local vertex debugging and the C# debugging experience! No spoil alerts here, but this video is definitely worth watching!
