One of the customers recently asked me “what happens when I click performance recording” in Tableau?
Now, what was surprising was, that this person, who is proficient in Tableau Desktop was asking me the question. Which made me wonder, why?
Why, did he just not click it himself and see what happens?
I think there is a mix of reasons behind why a lot of people haven’t clicked this option. Continue reading What happens when I click the Performance Recording in Tableau?
So, if you have worked with Tableau, this is a question you have either asked or have been asked (or at least) wondered about?
Why would you want to use a TDE (aka DATA Extracts)?
If you are in business side of things you will probably be wondering why you even need to make this decision. This is an IT decision, typically. isn’t it?
If you are on the IT end of the business (pun intended), you might say, what the heck?
I have to maintain another source of data?
so, let’s get some things straight today.
This article will help you understand the what, the why and the how if the TDEs.
well, at least my perspective on it, anyway.

Ok, so you ran a bunch of tests using TabJolt. What next?
You are probably here because you read the article on how to conduct scalability testing
The first thing that you should do is extract the data out of postgres rather than making live connections.
Then, you get confused with all the results that you see in the workbook. What are you supposed to make out of all those numbers?
If you have never done any test of this kind before, you are in for a surprise.
At Tableau, we like to keep things simple. But, unfortunately, a lot of you see those test results seem anything but simple.
Here’s my take on it.

- How will my user mix (viewer/interactor) impact my server capacity planning?
- How many VizQLs do I need for my user community?
- Can I configure 8 VizQL instances on a single server?
- …… to name a few.
The idea behind this post is to guide you on how to do some of your own tests to get some of the answers
So, lets get started and understand a few things about scalability tests
The idea is to understand how many users of a particular type of load can a server support
Now, since I currently work for Tableau and have had exposure to some of their tools, I used one of their tools (TabJolt) to conduct some of the tests
The rest of the article follows an approach. You can most certainly follow the same approach and use a completely different tool
