What’s New With In-Memory OLTP In SQL Server 2019

Ned Otter gives us two things to look forward to with SQL Server 2019:

So far, there’s been only one publicly announced enhancement for In-Memory OLTP in SQL 2019: system tables in TempDB will be “Hekatonized”. This will forever solve the issue of system table contention in TempDB, which is a fantastic use of Hekaton. I’m told it will be “opt in”, so you can use this enhancement if you want to, but you can also back out of it, which would require a restart of the SQL Server service.

But there’s at least one other enhancement that’s not been announced, although the details of its implementation are not yet known.

Read on to learn about this not-yet-announced update.
