How Far Can You Push Tabular? Birds of a Feather at TechEd 2013–North America #msteched #ssas #tabular

sqlbi — Mon, 20 May 2013 13:15:00 GMT

I and Alberto Ferrari will moderate the following Birds of a Feather session at TechEd North America 2013:

CODE: BOF-ITP21
TITLE: How Far Can You Push Tabular?
SPEAKER: A. Ferrari; M. Russo
TIMESLOT: June 5, 2013 at 1:30 pm
ROOM: 263

Abstract: Tabular is the new engine in SQL Server Analysis Services. It is an in-memory columnar database capable of unprecedented performance but… how far can we go with an in-memory database? Will you be able to load your data warehouse in-memory to obtain the best performance? What should you care about when building the DWH? What does “fast” mean? What about real-time data? Can you query many billions rows really fast? In this BOF we will show some theory and share some of our experience, but we will welcome your questions and experience, to build a round-table of experts in order to speak about this fascinating topic.

I really look forward to this event – I and Alberto have some experience using Tabular in many different scenarios, but every time we meet new people at conferences we discover that there are new challenges ahead. This session will be the place to discuss together where are the limits today. Much far than many people realize, in my opinion!

Interviewed in SQL Down Under podcast #sqlserver #ssas #powerpivot

sqlbi — Mon, 01 Apr 2013 18:03:00 GMT

I’ve been interviewed by Greg Low in SQL Down Under show 58, and this is *not* an April fool! We talked for one hour about Tabular, Multidimensional, Data Warehouse and just a little bit about music (you can discover which music genre I’m used to listen…).

You can hear this interview from the SQL Down Under Show 58 page (it is an MP3 format) and if you like it there are many other past shows available. The PodCast is also available on iTunes and you can hear other podcasts in SQL Down Under page on iTunes Preview.

LASTDATE dates arguments and upcoming events #dax #tabular #powerpivot

sqlbi — Mon, 01 Oct 2012 17:04:00 GMT

Recently I had to write a DAX formula containing a LASTDATE within the logical condition of a FILTER: I found that its behavior was not the one I expected and I further investigated. At the end, I wrote my findings in this article on SQLBI, which can be applied to any Time Intelligence function with a <dates> argument.

The key point is that when you write

LASTDATE( table[column] )

in reality you obtain something like

LASTDATE( CALCULATETABLE( VALUES( table[column] ) ) )

which converts an existing row context into a filter context.

Thus, if you have something like

FILTER( table, table[column] = LASTDATE( table[column] )

the FILTER will return all the rows of table, whereas you probably want to use

FILTER( table, table[column] = LASTDATE( VALUES( table[column] ) ) )

so that the existing filter context before executing FILTER is used to get the result from VALUES( table[column] ), avoiding the automatic expansion that would include a CALCULATETABLE that would hide the existing filter context.

If after reading the article you want to get more insights, read the Jeffrey Wang's post here.

In these days I'm speaking at SQLRally Nordic 2012 in Copenhagen and I will be in Cologne (Germany) next week for a SSAS Tabular Workshop, whereas Alberto will teach the same workshop in Amsterdam one week later. Both workshops still have seats available and the Amsterdam's one is still in early bird discount until October 3rd!

Then, in November I expect to meet many blog readers at PASS Summit 2012 in Seattle and I hope to find the time to write other article on interesting things on Tabular and PowerPivot. Stay tuned!
