In-Memory OLTP
Hello, Compañeros! You’ve heard of Hekaton and in-memory OLTP before, but what does in memory really mean for your database? Perhaps you have questions like I did, like how does in memory OLTP differ from disk-based tables? What data types aren’t allowed in in-memory tables? Is in-memory only an “on premises” feature or does Hekaton work in Azure too? Is there a minimum amount of memory required for in-memory tables? In Episode 34 of the SQL Data Partners Podcast, I’m going to talk about in-memory OLTP and in-memory tables with Jos De Bruijn. Jos is a Program Manager at Microsoft for SQL Server In-memory OLTP. I chat with Jos about how in-memory tables work and why they’re just as durable as traditional disk-bound tables. He lays out the whole process. Jos also answers common DBA concerns about them and discusses how to make them efficient and reveals the SQL Server 2016 features that affect in-memory OLTP. After that, we explore Jos’ favorite business tools and listen as he talks about what he’d do with a million dollars, what his favorite superhero power would be, and what advice he’d give to anyone in the SQL Family.
