I posted a variation of this question to the CouchDB user list and haven't received a response yet. I'm curious to know if anyone else has built a so-called "CouchApp"; a pure HTML/JavaScript application hosted directly within CouchDB. If so, how did you handle user authentication? I'd like to be able to create a typical login form (u...

I´m in touch with CouchDB and the idea of mapping its results to Scala objects, as well as find some natural way to iteract with it, came immediatly. But I see that Dynamic languages such as Ruby and Javascript do things very well with the json/document-centric/shchema-free aproach of CouchDB. Any good aproach to do things with Couch i...
I need to store JSON strings against string keys (that should be like 255 characters long). Only querying by key is necessary, so basically just a persistent hash table. It doesn't need to be very safe to write to, but should be kind of fast (few thousand writes per second on single box). If two processes happen to try to write the same ...

I've been playing with CouchDB (and the RelaxDB ruby library) but creating a view and then trying to access it causes a nasty non specific error. I stepped back a step because I thought RelaxDB might be incompatible with the CouchDB version I'm using(0.8.1), but even when I create a new database and equivalent views and call it by manual...

I'm trying to write a couchdb view that takes a created_at timestamp in a sortable format (2009/05/07 21:40:17 +0000) and returns all documents that have a greater created_at value. I'm specifically using couch_foo but if I can figure out how to write the view I can create it in futon or in the couch_foo model instead of letting couch_f...
How many database systems there are that use JSON for storage or transport? I know of: CouchDB MongoDB DBSlayer I remember I saw yet another vendor in a SO user's profile.
