Tableau Server - reports are loading very slow




The first problem of the Tableau server is that it is slower than the desktop version. Which kind of makes sense but still business users don't like it. Developers are happy as they don't much have to deal with the server version for the reports; they can simply fire up their Tableau Desktop and get the information quickly. But once deployed on the server, the performance degrades. Reports load slow. You keep seeing the loading icon and eventually get tired of it. Well, there are few things you can do. I am simply going to write down one by one, as they occur to me.

Clear the cache of the Tableau Server


Simple and straight forward. Don't ask me why right now but just do it.

  • Start TabAdmin
  • Stop the Tableau Server Service 
  • Clear the Cache.
  • Start the Tableau Server Service. 

Easy enough to say but how to do these steps? Here you go.

 The first step to using tabadmin is to open a command prompt as an administrator:




Go to Tableau server Bin folder.

cd "C:\Program Files\Tableau\Tableau Server\10.2\bin"

You're now ready to enter tabadmin commands.

tabadmin stop
tabadmin status
tabadmin clearcache
tabadmin start


And done! After the server restarts, check if your reports load faster. In my case, I saw there were too many connection handlers from the past which were not cleared. So after clearing the cache, my reports performance improved. Gotta find a way to automate this periodically.

Tableau - show value as 0 for No Data or Null

Image
Many times we come across this situation where two columns are being compared/subtracted/added etc. We must show a zero as people don't like blank. Blank technically does not mean zero but come to accounting/finance, people get confused. If there is no value, there has to be a zero so that when they download the Tableau report or export it to excel, there is a zero. Null means, there can be a problem in the data load and hence you don't see that value there. To remove the ambiguity, zero is needed. Here is how. The magic function is ZN (Zero Number). This will replace any null values with zero. If the number is null or empty zn function converts that null value to zero.If the number is not null  then tableau returns the same number. Lookup function will literally 'Look at' the specified column - in this case the same column (0) - and help replace null with zero. ZN(LOOKUP(SUM([Value]),0)) You can even correct the function right in the Measure Values pane. Yo...
