Stairway to SQL Server Extended Events
Erin Stellato, a Principal Consultant with SQLskills.com, explores the use of Extended Events as a diagnostic data collection tool or SQL Server. She describes how to define efficient low-overhead event sessions that exploit fully the vast number of events, as well as the powerful filtering and data collection options, offered by this new event collection infrastructure. She also demonstrates simple techniques to analyze event data and identify and troubleshoot the causes of poor SQL Server performance, such as long-running queries that consume vast amounts of CPU and I/O resources. It is time to embrace Extended Events and understand all that it has to offer, and Erin's stairway is the perfect place to start.

Stairway to Columnstore Indexes
SQL Server 2012 and later offer a very different type of index from the traditional b-tree, the in-memory columnstore index. These indexes use a column-based storage model, as well as a new 'batch mode' of query execution and can offer huge performance increases for certain workloads. But how are they built, how do they work, and why do they manage to have such a dramatic impact on performance? In this stairway, Hugo Kornelis explains all, with his usual mix of concise description and detailed demonstration.
