CSV report generator
Your task
Design a CSV report generator for a SaaS dashboard. A user clicks 'export', and the system produces a CSV of their data (could be a few rows or up to a few hundred thousand) and lets them download it. Small reports should feel instant; large ones can take a while. Describe how you generate the file and deliver it to the user without timing out the web request.
It covers
- Csv export
- Async generation
- Large files
