SQL Server 2019

Getting released just before the end of the year, SQL Server 2019 is now available in general release. While at first glance, it appeared this release was all about Big Data Clusters, and rightfully so–it brings ‘cloud first’ options to on-premises scenarios; however, it is not the only big feature. We spoke about some of the Polybase changes in Episode 180 and in this episode Javier Villegas guides us as we dive into some of the performance enhancements–and run out of time. This just means we need a few more episodes to dig into more features.

Episode Quotes

“It’s been a journey to get into SQL Server 2019. Every time that you get into a major SQL Server version, you say, ‘come on, what’s left?’”

“In this particular version, they are focusing very heavily on three pillars: performance, security and mission-critical availability.”

“This concept of notebooks is really great in where you can encapsulate your whole set of scripts in only one notebook and then share it with everybody, including the results.”
