Understanding Data Extracts in Tableau

A data extract in Tableau is a specialized and optimized form of data storage that Tableau uses to improve performance and enhance data analysis capabilities. Here are the key aspects of data extracts in Tableau:

1. Purpose of Data Extracts:

• Purpose: Data extracts are used to create a snapshot or a subset of your data from the original data source. These extracts are highly compressed, making them efficient for analysis in Tableau.

2. Improved Performance:

• Significance: Data extracts significantly enhance performance by allowing faster loading and interaction with your data. They are particularly beneficial when working with large datasets.

3. Data Extraction Process:

• Creation: Data extracts are created through a process known as data extraction. During this process, Tableau connects to the original data source and selects a subset of data to include in the extract.

• Customization: You can customize data extracts by choosing specific columns, aggregations, and filters to include, tailoring the extract to your analysis needs.

4. Data Extract (.hyper) File:

• File Format: Data extracts are saved in a Tableau-specific file format with a .hyper extension. This file contains the extracted data and the metadata needed for analysis.

5. Benefits of Data Extracts:

• Enhanced Performance: Data extracts are highly optimized for analysis, leading to faster response times and smoother interactivity in your visualizations.

• Offline Usage: Once created, data extracts can be used offline, allowing you to work without a live connection to the original data source. This is particularly useful for scenarios where internet connectivity is limited.

• Aggregations: Data extracts can be pre-aggregated, which means Tableau can summarize data in the extract, making it more efficient for visualizations that involve aggregations.
