Metadata contention in tempdb has historically been a bottleneck to scalability for some workloads running on SQL Server. SQL Server 2019 introduces a feature named memory-optimized tempdb metadata which effectively removes metadata contention for tempdb-heavy workloads. In this session, we will understand how this feature works, how it is implemented, and when it is beneficial to use. We will also compare it to other techniques such as in-memory OLTP to decide which approach performs best for a given workload.
