In one case using a four-core commodity laptop, for instance, the new technology delivered a 10X performance improvement on 173 million rows of data. Now, improvements in Tableau 9.0 make it even faster, Tableau said, with features that are designed to make the most of the user's underlying hardware. That makes it easy to stay in the flow and to answer the questions you have, freely experiment and try different things."įirst launched with Tableau 6.0, Tableau's Data Engine is an in-memory analytic database that's designed for fast queries. "We've tried to add the same thing to Tableau 9.0. "When you use Excel, you can just start typing in any cell to perform a calculation," Ajenstat said. The idea, Ajenstat said, is to help users "spend more time on data analysis than data wrangling."Īlso new in Tableau 9.0 will be the ability to perform calculations on an ad-hoc basis, similar to what's possible in Microsoft Excel. With version 9.0, Tableau will add data-preparation features designed to make it easier for users to clean the data they're about to work with. What that means is that SAS, SPSS and R files can now all be accommodated by the software, he said.Īnyone who works with data often knows that preparing it for analysis - "cleaning it up," in other words, to rid it of undesirable features such as empty rows - can be just as important as analyzing it. Tableau already supports more than 45 data sources out of the box, including Hadoop, Salesforce and Excel, but brand-new with version 9.0 is support for statistical files, said Francois Ajenstat, vice president of product management.
