Summary

Amazon QuickSight has introduced Multi-Dataset Relationships, allowing users to define logical connections between datasets and perform runtime joins. This new feature eliminates the need for pre-flattening tables, enabling more flexible data modeling within QuickSight Topics.

Amazon QuickSight has unveiled a significant new feature: Multi-Dataset Relationships. This enhancement empowers users to establish logical connections directly between various datasets within the platform. The core benefit is the ability to execute runtime joins during query processing, which streamlines data analysis. Previously, users often had to flatten multiple tables into a single dataset. Now, each table can remain an independent QuickSight dataset, with their interrelationships defined and managed within a QuickSight Topic, offering greater flexibility and efficiency in data modeling.

Why it matters

Data professionals can now build more agile and less redundant data models in Amazon QuickSight, improving query performance and simplifying the management of complex analytical environments.

How to implement this in your domain

  1. 1Explore the new Multi-Dataset Relationships feature within Amazon QuickSight.
  2. 2Identify existing flattened datasets that could benefit from being broken into related individual datasets.
  3. 3Define logical relationships between your QuickSight datasets using the new capability.
  4. 4Test query performance and data accuracy with the new multi-dataset relationships.
  5. 5Update data modeling best practices and documentation for your team.
