Advanced Statistics Techniques for Advanced Query Performance

Slow queries? Want to speed them up? Query optimization statistics are probably the most important information that the optimizer uses to determine how to execute a query. But the statistics that are created with an index, or by default on a column when referenced in a predicate, are not always enough information for the optimizer to make “good enough” plan choices. That’s when you need to step in and manage statistics yourself. In this session, after a brief overview of what statistics are, we’ll explore how creating filtered statistics, creating statistics on multiple columns, or overriding the default maintenance of statistics can help.

DevOps and Databases: An Intro

DevOps has quickly become one of the most effective methods of Managing and Deploying a rapid and responsive release cycle. And too often, it seems like just another ‘buzzword’ to understand and sort out. In this brief overview, we’ll examine:
• Just what does DevOps mean for the Database Developer and Administrator?
• How does it impact and change ‘normal’ database operations?
• What do you need to know?
• What tools and services will be required?
• What are the Tips and Traps for incorporating databases into a DevOps approach to deployment management?
