This book, SQL Server Internals: In-Memory OLTP is a true gem for modern data developers and data professionals. It contains an unprecedented level of details about the in-memory technology of SQL Server. In my many conversations with customers, I often hear a confusion between the terms "In-Memory" and "Memory-Optimized." Many think that they are one and the same. If you continue reading this book, you will realize the distinction. In-Memory OLTP is a game changer for relational databases, and especially for OLTP systems.
