Tabular Performance Guide Speaking Tour

Some of the most fun I’ve had this year was spent collaborating with some friends at Microsoft to publish an important guide on performance tuning Tabular models in Analysis Services. I am very proud to have helped co-author the paper which represents hundreds of hours of work by many people.

Performance Tuning of Tabular Models in SQL Server 2012 Analysis Services

The reaction from the community has been great (here and here for example). Chris Webb even noted that there is some content in the whitepaper relevant to Multidimensional models, too. Specifically he mentioned we noted in the whitepaper that SQL 2012 SP1 CU4 (though you should just skip to CU6 which is the latest at the moment) included an enhancement so that multi-select filters no longer prevent caching in most scenarios. While that is a huge deal for Multidimensional models, it’s also very helpful for Tabular models if you’re querying them in a client tool like Excel which runs MDX queries. For those who are optimizing Multidimensional models, I’d also point you to a summary of SSAS enhancements made in SSAS 2012 on page 144, a warning about very wide models and heap fragmentation on page 67, and a discussion of updated SSAS drivers and performance on page 69.

PASS Summit 2013

John Sirmon and I had the privilege of summarizing 147 pages of content into a 75 minute presentation at PASS Summit 2013 in Charlotte, NC recently. The room was pretty packed and there were some great questions afterward.

SQL Saturday #255 – Dallas

For the locals who weren’t able to make it to Charlotte, I’m going to be doing the talk in my hometown for SQL Saturday Dallas on November 2, 2013. Here’s the abstract:

Gain the knowledge, tips, and techniques you need to tune your Tabular models in SQL Server Analysis Services 2012. This session will begin by exploring the Tabular model architecture and explaining the factors that affect performance. We’ll then walk through tuning techniques and strategies specific to querying, processing, partitioning, and server configuration and demonstrate optimizing performance in some common scenarios. This session is based on the recently released white paper “Performance Tuning of Tabular Models in SQL Server 2012 Analysis Services.”

Tabular Performance Event

It’s hard to do justice to this content in an hour, so I am looking forward to speaking at an all-day event at our local Microsoft office in Irving, TX on November 12, 2013. If you are interested, please reach out to Bryan Smith.
