Deadlocks,A deadlock is a special blocking case that occurs when multiple sessions—or sometimes multiple execution threads within a single session—block each other. When it happens, SQL Server terminates one of the sessions, allowing the others to continue.

Application Locks,This chapter will discuss another SQL Server locking feature called application locks, which place locks on an application resource identified by name. Application locks allow you to serialize access to T-SQL code, similar to critical sections and mutexes in client applications.

Troubleshooting Concurrency Issues,System troubleshooting is both an art and a science. It is also a very big and complex topic. If I had to write a book covering all aspects of system troubleshooting, it would have more pages than the one you are currently reading.

In-Memory OLTP Concurrency Model,The In-Memory OLTP technology, introduced in SQL Server 2014, can significantly improve the performance and throughput of OLTP systems. The key technology component—memory-optimized tables—stores the data in-memory, utilizing lock- and latch-free multi-versioning concurrency control.

Locking in Columnstore Indexes,Columnstore indexes are a type of index that stores data on a per-column rather than per-row basis. This storage format benefits query processing in data warehousing, reporting, and analytics environments where, although queries typically read a very large number of rows, they work with just a subset of the columns from a table.
