In-Memory OLTP In SQL Server 2017

Ned Otter walks us through all of the changes to memory-optimized objects coming in SQL Server 2017:

  • Up to and including SQL 2016, the maximum number of nonclustered indexes on a memory-optimized table was eight, but that limitation has been removed for SQL 2017. I’ve tested this with almost 300 indexes, and it worked. With this many supported indexes, it’s no wonder they had to….

  • Enhance the index rebuild performance for nonclustered indexes during database recovery. I confirmed with Microsoft that the database does not have be in SQL 2017 compatibility mode (140) to benefit from the index rebuild enhancement. This type of rebuild happens not only for database restore and failover, but also for other “recovery events” – see my blog post here.

Read on for several more improvements, as well as a couple of things which Ned would like to see but aren’t there yet.

I responded as I always do: it’s not possible to set a limit on anything having to do […]
