How to Enable Pagination in Apache Superset Table Charts?

  

In this post, we explore how to enable pagination in table charts within Apache Superset dashboards to efficiently handle large datasets.

 

What is Pagination?

Pagination is a technique used to divide large amounts of data into smaller chunks called pages. Instead of loading thousands or millions of records at once, the application loads only a limited number of records per page.

 

For example:

Page	Records Displayed
Page 1	1 - 10
Page 2	11 - 20
Page 3	21 - 30

 

This improves:

·      Application performance

·      Dashboard loading speed

·      Database efficiency

·      User experience

·      Browser memory usage

 

Pagination is commonly used in:

·      BI dashboards

·      Table visualizations

·      E-commerce websites

·      Search results

·      Admin panels

·      Reporting systems

 

Why Pagination is Important?

Imagine a table containing:

 

·      10 million product records

·      50 columns

·      Multiple joins and aggregations

 

If the application tries to load everything at once:

 

·      Database query becomes expensive

·      Browser becomes slow

·      Dashboard may freeze

·      Network transfer increases

·      Memory usage becomes high

 

Pagination solves this problem by loading only the required subset of data.

Example 

SELECT *
FROM products
LIMIT 10 OFFSET 0;

   

Only 10 rows are fetched instead of millions.

 

Follow below step-by-step procedure to enable pagination.

 

Open table chart in  Superset.

 

Click on the checkbox ‘Server pagination’, set Server Page Length of your choice.

 

Click on ‘Update chart’ button.

 

You can be able to see that the table chart is rendered with Pagination support.
