SQL Server 2019 In Memory tempdb

In this video, I explore an interesting improvement in SQL Server's TempDB management, specifically focusing on how certain metadata can now be stored in memory to reduce contention. I walk through the process of enabling this feature by turning on advanced options and setting a specific configuration setting, which requires a server restart for changes to take effect. Despite these improvements, I also demonstrate that some system views still require locking mechanisms, leading to potential contention issues even with TempDB metadata stored in memory. By using SQL Query Stress, I show how creating multiple temporary tables can result in blocking without visible locks through spWhoIsActive, highlighting the ongoing challenges and areas for further optimization in TempDB management.
