Microsoft SQL Server 2017: Fast, faster, and the fastest database everywhere you need it
“I feel the need, the need for speed”. That is a quote from the character Maverick, played by Tom Cruise, in one of my favorite movies, Top Gun. It makes me think of one of the top reasons why someone chooses a database engine. It must be fast and perform to the needs of all types of workloads accessing data.
SQL Server 2017 sets the standard when it comes to speed and performance. Based on the incredible work of SQL Server 2016 (See the blog series It Just Runs Faster), SQL Server 2017 is fast: built-in, simple, and online. Maybe you caught my presentation at Microsoft Ignite where I demonstrated 1 million transactions per minute on my laptop using the popular tool HammerDB¹ by simply installing SQL Server out of the box with no configuration changes (with the HammerDB client and SQL Server on the same machine!)
Consider for a minute all the built-in capabilities that power the speed of SQL Server. From a SQLOS scheduling engine that minimizes OS context switches to read-ahead scanning to automatic scaling as you add NUMA and CPUs. And we parallelize everything! From queries to indexes to statistics to backups to recovery to background threads like LogWriter. We partition and parallelize our engine to scale from your laptop to the biggest servers in the world.
Like the enhancements we made as described in It Just Runs Faster, in SQL Server 2016, we are always looking to tune our engine for speed, all based on customer experiences. Take, for example, indirect checkpoint, which is designed to provide a more predictable recovery time for a database. We boosted scalability of this feature based on customer feedback. We also made scalability improvements for parallel scanning and consistency check performance. No knobs required. Just built-in for speed.
One of the coolest performance aspects to built-in speed is online operations. We know you need to perform other maintenance tasks than just run queries, but keep your application up and running, so we support online backups, consistency checks, and index rebuilds. SQL Server 2017 enhances this functionality with resumable online index builds allowing you to pause an index build and resume it at any time (even after a failure).
