In Microsoft SQL Server 2019 and 2016, two new XEvents, temp_table_cache_trace and temp_table_destroy_list_trace, are created for tracking Temp Table Cache metrics and operations. 

Note These XEvents track a specific metadata cache object ("temporary object cache") that contains information about which temporary tables, objects, and parameters are cached, evicted and reused.
