So in clustering couchdb everyone recommends haproxy but I do t want to pay
the price for an extra hop. Is there a better solution out there?.. I'm
thinking of pulling they keyspace doc in myself and just have a collection

My question is is the extra hop really that irrelevant ?... Or is their and
obvious load balancing trick I'm missing?
The extra overhead of the extra hop is pretty much irrelevant for
anything Internet-based. The reason is that the end user will see at
*best* about 20ms to you, and haproxy won't even add 1. Since the
"typical user"** will see more like 50ms, the 0.1ms or so of overhead in
a proxy is irrelevant if it gives you better uptime.

burning through thousands of queries per second?
