Import Hadoop Data into SQL BI Semantic Model Tabular

by dennyglee Categories: Analysis Services · BigDataTags: · Leave a comment

Originally posted on Ayad Shammout's SQL & BI Blog:
  Hadoop brings scale and flexibility that don’t exist in the traditional data warehouse. Using Hive as a data warehouse for Hadoop to facilitate easy data summarization, ad-hoc queries, and the analysis of large datasets. Although Hive supports ad-hoc queries for Hadoop through HiveQL, query performance is often prohibitive for even the most common BI scenarios. A better solution is to bring relevant Hadoop data into SQL Server Analysis Services Tabular model by using HiveQL. Analysis Services can then serve up the data for ad-hoc analysis and reporting.

by dennyglee Categories: Analysis Services · BigDataTags: · · · 1 Comment

About three and a half years ago, I had virtually joined the Yahoo! Targeting, Analytics, and Optimization (TAO) Engineering team where we embarked on an incredible journey to create the largest single instance Analysis Services cube.  Mind you, that was not our actual goal – our actual goal was to create fast interactive analytics against a massive amount of display advertising data from Yahoo! sites.  The requirements were staggering as noted in the slide below.   Ultimately, we took 2PB of data from one of Yahoo!’s large Hadoop cluster and created a 24TB Analysis Services cube so users could do…

Yahoo! 24TB SSAS Big Data Case Study + Slides

by dennyglee Categories: Analysis Services · BigDataTags: · · 9 Comments

In my post from last year, I had asked the rhetorical question What’s so BIG about “Big Data”.  I had the honor of announcing the largest known Analysis Services cube – at 24TB – in which the source of this cube is 2PB from a huge Hadoop cluster. For those whom had attended the PASS 2011 session Tier-1 BI in the world of Big Data, Thomas Kejser, myself, and Kenneth Lieu were honored to discuss the details surrounding this uber-cube.   At that time, I had promised the case study would only be months away… Alas, it took a little while…
