Feature request: specify multiple Couches for a connection

[indexzero]

We had an outage today at Nodejitsu. The physical hardware for our Couch server at Rackspace went down. We didn't have replication setup, but now we do.

In these doomsday scenarios it would have been nice to be able to specify both the primary and backup CouchDb servers in the cradle.Connection instance and have it automatically begin to failover. I don't see any other way to solve these kinds of problems.

You could catch the error when node dies and switch to using the backup servers then. This isn't an issue specific to cradle, but to any network connections needed by your app. cradle would get really bloated to have a feature like this. There's also the issue of when to switch back to primary...

@mikepb I don't think it would "bloat" the library, but you're probably right that it should be a separate library that cradle could later take as an upstream dependency.

Be aware that I don't plan on using this feature, so I won't find any bugs. Also note that you must now provide host arguments to new cradle.Connection() in the options hash.

@mikepb Thanks! Also, interesting. Have you just completely given up on merging anything back into the mainline fork?

[mikepb]

Meh. mainline is dying...
