How backend works when joining datasets

Hello @hoyeon

Thank you for the follow up questions.

Timeout: QuickSight enforces a 2-minute timeout for visual generation. If the Direct Query exceeds this time, the visual may fail to load.

I would suggest you to have a look on these blogs, they are really very insightful and provides the required answers.

  1. Best practices for Amazon QuickSight SPICE and direct query mode
  2. SPICE and Direct Queries for Enhanced Data Analytics and Visualization
  3. Joining across data sources on Amazon QuickSight | AWS Big Data Blog

Let me know if these helps.

Thank you,
Shravya
