Latches, Spinlocks, and Lock Free Data Structures
Join this session to make a deep dive into how SQL Server implements physical locking with lightweight synchronization objects like Latches and Spinlocks.
You know locking and blocking very well in SQL Server? You know how the isolation level influences locking? Perfect! Join me in this session to make a further deep dive into how SQL Server implements physical locking with lightweight synchronization objects like Latches and Spinlocks. We will cover the differences between both, and their use-cases in SQL Server. You will learn about best practices how to analyze and resolve Latch- and Spinlock contentation for your performance critical workload. At the end we will talk about lock free data structures, what they are, and how they are used by the new In-Memory OLTP technology that is part of SQL Server 2014.
