Newbie question: I want to analyze a large dataset from a Datanet query. Data file is too large to import. When I click on the link for: Looking to add data for visualizations and analysis? Go to data sources, I get a 404 error, page not found. Cannot see how to input a dataset into a space.

Hi @vbors

Welcome to the Quick Suite community!

If your large dataset files are stored in S3, connect via Athena data source for querying S3 data without full import. Please refer to the following documentation this might be helpful for you.

For Spaces (Q chat/topics): Datasets are account wide, create first, then add via `Topics -> Create topic -> Add datasets`. Refer this [Connect Datasets to Spaces](https://community.amazonquick.com/t/how-can-we-connect-a-quicksight-dataset-to-chat-agent-spaces-does-not-allow-connecting-to-a-dataset/51539/5)
