Paperclip, Delayed Job, S3, Heroku - design for delayed processing of sensitive uploaded files: db or s3?

Question

I need feedback on the design for uploading and delayed processing of a file using heroku, paperclip, delayed job and, if necessary, s3. Parts of it have been discussed in other

Answer 1

For my part I'm using :

• Delayed Job
• Paperclip
• Delayed Paperclip which uploads the original file on S3 and create a delayed job with the custom post processing. It can add a column to you model stating that the file is being processed.

Only a few lines to set up. And you can do a lot with paperclip interpolations and generators.
