tue20oct9:00 AM9:40 AMI will speak at SQL DaysPerformance Tuning with Optimistic Concurrency in Microsoft SQL Server9:00 AM - 9:40 AM CEST Erdinger Stadthallen GmbH, Alois-Schießl-Platz 1, 85435 Erding, Germany



The default transaction isolation level of SQL Server is set to read committed, which eliminates certain read phenomena, but can also affect concurrency and overall read performance.
SQL Server also offers two optimistic transaction isolation levels where a transaction does not acquire a lock when reading data, which reduces the probability of blocks and therefore leads to significantly better reading performance in a busy database.
In this session (level 300), you will learn how to increase the reading performance in a database simply by changing the transaction isolation level to snapshot isolation. You will also understand how SQL Server implements this function internally and what disadvantages it has.
