I'm developing a Rails 2.3, Ruby 1.9.1 webapplication that does quite a bunch of calculation before each request. For every request it has to calculate a graph with 300 nodes and ~1000 edges. The graph and all its nodes, edges and other objects are initialized for every request (~2000 objects) - actually they are cloned from an uncalcula...

Has anybody succeeded in sending standalone attachments using the standalone attachment API (if possible gziped) to couchDB from ruby? I know there are a few CURL examples, but my tries with Typhoeus haven't been successful so far. It usually just stops and waits for > 1 minute after the first few documents. CouchRest doesn't seem to sup...
