SQL Server According to Bob

SEPTEMBER 26, 2016

When we released Always On Availability Groups in SQL Server 2012 as a new and powerful way to achieve high availability, hardware environments included NUMA machines with low-end multi-core processors and SATA and SAN drives for storage (some SSDs). As we moved towards SQL Server 2014, the pace of hardware accelerated.

The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. Hardware Past As Performance Prologue. Regardless, the overall story for hardware progress remains grim, particularly when we recall how long device replacement cycles are: Tap for a larger version. Mind The Gap. Tap for a larger version.

Internally DBCC CHECK* uses a page scanning coordinator design (MultiObjectScanner.) SQL Server 2016 changes the internal design to (CheckScanner), applying no lock semantics and a design similar to those used with In-Memory Optimized (Hekaton) objects, allowing DBCC operations to scale far better than previous releases.

My development collogues and I are starting a regular blog series, outlining the vast range of scalability improvements, allowing SQL Server 2016 to run across a wide array of hardware configurations, faster and better than previous releases of SQL Server. Where SOS_RWLock is used, no matter the SKU, the new design applies.

We designed DynamoDB to operate with at least 99.999% availability. The original Dynamo paper inspired many database solutions, which are now popularly referred to as NoSQL databases. These databases trade off complex querying capabilities and consistency for scale and availability. NoSQL and Flexibility: Document Model.
