Yeah. Another one of those questions. But with all that is out there, I loose track and choosing the right system greatly influences wether you can work on what you love or work around what appears missing. So:
I am building an app that stores multi resolution images. These two features seem to push me away from CouchDB/PouchDB:
you upload the RAW (or any other high-rez source) and it builds a thumbnail and a medium rez. Already have this covered. Mobile users only get the thumbnails and DL the medium rez as needed. Desktop users get thumbnails and medium rez and DL the RAW as needed.
your images are your own. you can choose to share an image with another user and you are able to revoke this right.
So I liked CouchDB and PouchDB, but the per-db security model would appear to cost a lot of work to get to behave like I want. And not replicating higher rez is also somewhat of a headache. I do want to stick to NoSQL, because I am still working this out and want to be able to change the schema. A lot.
Any suggestions?
