AWS S3 + Leina: Your Questions, Answered
What can I upload?
The upload action accepts a public source URL, plain text, or encoded file bytes. Provide exactly one content source and the destination bucket and object key.
Does a pre-signed download URL make the bucket public?
It grants the URL holder the specified object operation for a limited time; it does not change bucket policy. For downloads, request a GET URL with an appropriate expiration.
Can AI summarize a file from an object listing alone?
An object listing provides keys and metadata. Content must be downloaded separately and processed by an AI product that can read the file format.
