Does Redis support file caching?

Question

I am working on an app in Ruby on Rails that requires frequent fetching of text files. These files are modified very rarely. Currently the files are fetched from Amazon s3. I would like to create a cache so that I can save on network time. I would prefer in-memory cache rather than writing on filesystem. Is it possible to use Redis or Memcached to store the files? If not what are my other options?

Answer 1

Redis can be used for storing any data, the only limitation is that its protocol supports strings of up to 512MB - if your files are smaller than that, there shouldn't be any problem.
