5 Best Practices for Tableau & Hadoop

Overview | What you'll learn: 

Tableau was designed to facilitate real-time conversations with data across multiple data platforms. Business users who have felt stymied by traditional tools have flocked to this modus operandi. So what happens when queries return in hours or minutes rather than seconds? Can their ‘flow’ be maintained?

We are in an age where people can analyze millions or even billions of rows of data at their fingertips yet a user’s expectations is that they have near instantaneous results. When a user’s interactions and response times take more than 2-3 seconds, they become distracted from being “in the flow of visual analysis.” Thus, it is imperative to provide fast query speeds to keep users engaged so that they can gain more insight from their Big Data deployments.

Users can apply a number of best practices to maximize the performance of their Tableau visualizations and dashboards built on Big Data platforms. The best practices largely fall into the following five activities:

  2. Strategically Utilize Live Connections Vs. Extracts
  3. Curate Your Data From The Data Lake
  4. Optimize Your Extracts
