The Amazing KQL

Hello Everyone!
Thank you for visiting The Amazing KQL!
I have been learning how to use KQL for some time now, I found it so fascinated and decided would like to create a page of my learning journey.
So the first question will be. What is KQL?
KQL is from Kusto Query Language
But again, what is Kusto Query Language? Where's the name is coming from? Well, you must read Rod Trent's Must Learn KQL series. In Part 2: Just Above Sea Level, he told us his childhood story. Quote from Rod's story:
KQL is named after Jacques Cousteau
