In February 2012 I began working for a new company. Back in 2012, my CTO was passionate about “every developer pushing [meaningful] code to production on their first day”. You might want to have a pen test or peer-to-peer check of any new service before it goes live, and that can delay things. I was lost for words.

For SQL Server 2012 and earlier , the transition point for this particular table is 898 rows. An example call stack is shown below: The essence of the test is: The insert must be for more than 250 rows.

The rapid acceleration in technology brought on a new discovery and paradigm.

It’s not just that an older device will be less equipped to deal with the complexity of today’s sites, but also that it’s far less likely that the folks building those sites will have tested on your device. This is a point Cennydd Bowles made in his excellent book, Future Ethics. Again, this isn’t hyperbole.

Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes. This issue is valid for on-premises, IaaS, and partially for Azure SQL Managed Instance.
