Methods to Set up Tableau Real Time Data Streaming

Tableau Real-Time Data Streaming is a way to ensure that companies extract insights from up-to-date data in order to make the right business decisions. It can be set up using the 2 following methods:

Method 1: Using Custom Code Snippets to Set Up Tableau Real Time Data Streaming

Tableau is not a natively live streaming tool. So, if you want to perform Tableau Real-Time Data Streaming, you have to write a script or code that will perform the required operations for you. In real time streaming, the data is supposed to be refreshed without the involvement of the user.

In most connections to Tableau, you refresh the data in your desktop by right-clicking the data connection and choosing “Refresh”. You can also use the menus where you’ll find the refresh option.

The easiest way to refresh your data source is by clicking the F5 key on the keyboard. If you’re using Tableau Server, you can refresh the data source by clicking the refresh icon located at the top of the view. 

Tableau Desktop Auto-Refresh

If you’re using Tableau Desktop to set up Tableau Real Time Dashboard and you want to refresh your data after every 5 minutes, first download and install an open-source utility called AutoHotKeys from here.

You can then use the following script:

#NoEnv; Recommended for future AutoHotkey releases.
; #Warn; Enable warnings to assist with detecting common errors.
SendMode Input; Recommended for new scripts 
SetWorkingDir %A_ScriptDir%; Ensures a consistent starting directory.

SetTimer, PressTheKey, 300000

Send, {F5}

Tableau Server Auto-Refresh

If you’re using the Tableau Server, you can use the Tableau JavaScript API to set up Tableau Real Time Data Streaming. The following JavaScript API will refresh your Tableau Server data after every 3 seconds. 

Note that it cannot work on Tableau Desktop.

<!DOCTYPE html>
<html lang=“en”>
<title>Tableau JavaScript API</title>
<script type= “text/javascript” src=“”></script>
<div id=“tableauViz”></div>

<script type=‘text/javascript’>
var placeholderDiv = document.getElementById(“tableauViz”);
var url = “”;
var options = {
hideTabs: true,
width: “100%”,
height: “1000px”
var viz = new tableauSoftware.Viz(placeholderDiv, url, options);

setInterval(function () {viz.refreshDataAsync() }, 3000);


The value of the URL variable has to be replaced with the URL of your Tableau workspace. If you want the refreshing to be done after every 5 minutes, replace the 3000 in the fourth line from the bottom with 300,000. 

This is the best solution provided you have a quick data connection.

Limitations of Using Custom Code Snippets to Set Up Real Time Data Streaming in Tableau

Although it is possible to achieve Tableau Real Time Data Streaming with the above approach, you will encounter the following challenges:

  • Coding experience and knowledge of JavaScript is required. This means it’s not the right approach for non-programmers. 
  • It may not work well in cases of a slow data connection.
