How to integrate my Amazon Redshift Warehouse with Tableau?


Tableau is a business intelligence (BI) tool, that makes data more accessible and understandable by means of data visualization in the form of dashboards. The interactive dashboards offered by Tableau enable a better comprehension of data, leading to meaningful insights. This helps businesses leverage the power of data for informed decision-making. Thus, Tableau makes it easy for you to create effective and engaging dashboards, using data from a variety of sources.

In order to link your Amazon Redshift Data Warehouse to Tableau, you will need to install Tableau desktop.

Steps to Connect Amazon Redshift to Tableau

  1. Before you begin, you’ll be required to allow access to Amazon Redshift resources.

  2. Open your AWS admin console.

  3. Search for Redshift in the search box and from the search results, click on "Amazon Redshift".

  5. Copy the "Endpoint URL" from the General Information. This will have a format: {cluster_url}:{port}/dev. cluster_url is your Host Name. The “Endpoint URL” also gives you the details of Amazon Redshift Database Port Number (see format).
