Be My Azure DBA (DSA) by Paul Andrew

10/2/2018
More
There seems to be a common misconception that once you move from on premises SQL Server to Azure PaaS offerings a DBA is no longer required. This perception is wrong and in the session I’ll show you why. As a business intelligence consultant I develop data platform solutions in Azure that once productionised need administration. As the title suggests, be my Azure DBA. Maybe not DB for database. Maybe in Azure I need a DSA, a Data Services Administrator. Specifically we’ll cover a real...

The Perfect Index by Arthur Daniels

9/25/2018
More
Creating indexes is one of the most powerful ways to improve performance in your SQL Servers. It's not easy to form indexes for a large and complicated query, and things only get more complicated when queries can come from vendor applications, ORM tools like LINQ, or any number of other sources. When it's time to create the perfect index, there's guidelines and strategies to get it right, and then prove that it's helping. However, performance is not always about just one index, and general...

Not just polish – How good code also runs faster by Daniel Hutmacher

9/18/2018
More
I want to show you how just a little neater and tighter code can also run a lot faster. These are some of the instant performance improvements that won’t change a lot of code, won’t generate weeks of testing and validation for your colleagues and can be relatively quick to implement. But most of all, they’ll make the code prettier and easier to understand for the next person. We’ll look at common ways that null values, implicit datatype conversions and foreign key constraints can radically...

You've been writing T-SQL queries for a few years now, and when you have performance issues, you've been updating stats and using OPTION (RECOMPILE). It's served you well, but every now and then, you hit a problem you can't solve. Your data's been growing larger, your queries are taking longer to run, and you're starting to wonder: how can I start getting better query plans?

Columnstore Clustered vs Nonclustered, When to Choose What by Niko Neugebauer

6/12/2018
More
The incredible Columnstore Indexes can increase your analytical query processing speed multiple times, they are updatable (Clustered from SQL Server 2014 and Nonclustered from SQL Server 2016 respectively), but they keep on supporting different sets of the functionalities – such as Change Data Capture (Nonclustered Columnstore) or LOBs (Clustered Columnstore), and this brings a great confusion onto the table. This session will light up your path on when to use what functionality to use and...
