Always Encrypted & Memory Grant Feedback in SQL Server

The first part of the demo talks about Always Encrypted. It shows the importance of Column Master Key(CMK) and what happens if we don't posses it. Later we compared Always Encrypted with Column Level Encryption and finally bit about Enclaves. Later part of the demo is on Memory Grant Feedback which is there from SQL 2017. I explained these with proper demos by underestimating and overestimating the statistics and how it affects the performance and how SQL Server would adjust the memory Automatically. Kindly spare some time as these demos helps a lot in understanding these Concepts.
