: A visual indicator showing the number of files processed (e.g., "150,000 / 455,000 zipped") to manage expectations during long tasks. Technical Requirements
A download feature for a large file (likely meaning either 455,000 files or a 455 GB archive) requires balancing speed, reliability, and clear user communication. Feature Specification: "DeepData Archive Download" Overview
: Large files are automatically split into smaller, more manageable volumes (e.g., 5GB–10GB chunks). Download 455K zip
: Smaller ZIPs reduce the risk of a total failure on unstable connections; if part 5 fails, the user only restarts part 5.
: Instead of an immediate download, the system "prepares" the ZIP in the background. : A visual indicator showing the number of
Allow users to export and download massive datasets containing up to 455,000 records or large multi-gigabyte ZIP archives without exhausting server memory or timing out browser connections.
: Use Stream-Based Processing . The server should read chunks from the database/storage and write them directly to the response output stream rather than loading the entire 455K dataset into RAM. : Smaller ZIPs reduce the risk of a
: Implementation of HTTP Range Requests (Status 206) to allow users to pause and resume progress.
