Memory-Optmized TempDB Metadata was introduced in SQL Server 2019 and is a part of the In-Memory Database feature family. This feature was introduced in order to improve the scalability of highly-concurrent OLTP applications by leveraging latch-free non-durable memory-optimized tables for TempDB system tables. Enabling this feature effectively removes metadata contention - a common bottleneck for highly-concurrent TempDB workloads.
