What's wrong with Ruby libraries for CouchDB?

During the last year, I have worked on couple of Ruby/Rails based projects where the primary datastore was CouchDB. CouchDB, to me, is a dream database for web developer come true. The simplicity, the HTTP-based API, the abandonment of SQL semantics, the inspiring community, that all reminds me of when I came into Rails years ago.

However, working with Couch in Ruby and Rails is very, very painful, in my opinion. I'd like to briefly summarize some of my frustrations here. Maybe they are shared, maybe not -- if they are, I think we should launch some coordinate effort to make using Couch in Ruby a pleasure and intelectual satisfaction, not endless loops of research and hacks to „make it work“.

Please note, that my interest is solely to stir the debate. I may be severely mistaken in any point. But, I'd like using Couch in a Ruby application to be a joy, not a frustration, which is what I've met more times than I'd ha

1. Introduction to the replicator database

A database where you PUT/POST documents to trigger replications and you DELETE to cancel ongoing replications. These documents have exactly the same content as the JSON objects we used to POST to /_replicate/ (fields "source", "target", "create_target", "continuous", "doc_ids", "filter", "query_params".

Replication documents can have a user defined "_id". Design documents (and _local documents) added to the replicator database are ignored.

The default name of this database is _replicator. The name can be changed in the .ini configuration, section [replicator], parameter db.

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

A list of features that we want to see in CouchDB. Needs to be voted on so that it can become a priority queue.

User Facing Features
====================

1. Conflicts are the rule, not the exception

All previous versions of CouchDB hide conflicts by default (selecting
an arbitrary but consistent winning revision). Expert users can find
and resolve conflicts.
