Thanks for your comment.
As for your que...Brenda,<br /><br />Thanks for your comment.<br /><br />As for your question - the field consisted of 12 character strings with roughly 70M unique values. I could perform the same test on a field with significantly less unique values, but then the results would be misleading because even a simple RDBMS could handle that within the same time frame as Tableau's engine by performing an index scan (which I believe what Tableau's engine does really).<br /><br />It's important to understand that the purpose of this post is not to determine a definitive 'fast' or 'slow' grade. This is a technological post that aims to *compare* between existing data engines and Tableau's new data engine (i.e. slowER or fastER)<br /><br />Fast or slow really depends on what you're doing and what you expect within the scope of the use case involved. A 30 minute response time for a distinct count, like I've shown, could be 'fast' or 'slow' too. It depends on what you're doing.Elad Israelihttps://www.blogger.com/profile/14039349385755633029noreply@blogger.comtag:blogger.com,1999:blog-8489991802309187017.post-35086193325601305272010-11-16T06:36:36.028-08:002010-11-16T06:36:36.028-08:00I've used the new Tableau on hundereds of mill...I've used the new Tableau on hundereds of millions of rows and I agree with Jim - for the data I use it is very fast. <br /><br />Which makes me wonder about your test. What sort of text field were you trying to insert? Was it just half a billion lines of web log entries, all different? Did you try anything else, like half a billion rows of numbers? Half a billion rows of dates? Half a billion rows of country names? <br /><br />That's the kind of "real world" data I am trying to analyze and so far it has been amazing.Brendanoreply@blogger.comtag:blogger.com,1999:blog-8489991802309187017.post-8201706065433584052010-11-14T12:18:08.484-08:002010-11-14T12:18:08.484-08:00Jim,
Thank you for your comment.
SiSense and Tab...Jim,<br /><br />Thank you for your comment.<br /><br />SiSense and Tableau are hardly competitors. Tableau is a visualization tool while SiSense is a development environment for creating enterprise-grade BI solutions with centralized data repositories. SiSense competes on the same deals as QlikView, IBM, SAP etc.<br /><br />My sole interest in Tableau’s new release is the technological aspects of their new data engine, not their product (note the title of this post). The portions I removed from Tableau CEO's quote are those who have no bearing on the data engine that is being discussed here.<br /> <br />The test we’ve conducted is on ONE field, which is considered the simplest test there is. There is no way to ‘optimize’ a single field for anyone’s product. You’ll notice that in this post I am also comparing QlikView’s technology (a direct competitor of SiSense) to Tableau’s – exactly to avoid claims of subjectivity. As you may have noticed, QlikView have done quite well on this benchmark, so any claims of bias are invalid.<br /><br />As for your own experience – publish your data set properties, hardware used and benchmark results and I’ll be happy to review it. I can’t really comment on claims like ‘It is fast like nothing else’, unless ‘nothing else’ means Tableau 5.2 in which case I would totally take your word for it.<br /><br />Thanks again,<br />EladElad Israelihttps://www.blogger.com/profile/14039349385755633029noreply@blogger.comtag:blogger.com,1999:blog-8489991802309187017.post-72786063610952697632010-11-14T06:30:30.359-08:002010-11-14T06:30:30.359-08:00Do I have this right?

You do 1 test that is probably optimized to your product. <br /><br />I'm a Tableau user and I've been using their new product analyzing 212 million records. It is fast like nothing else. I didn't have to write any scripts or programs. It just worked.Unknownhttps://www.blogger.com/profile/07305135917463312462noreply@blogger.com
